0:00 INTRO: In this video we solve a combination series and parallel resistive circuit problem for the voltage across, current through and power dissipated by the circuit's resistors.
1:32 BREAK IT DOWN: We redraw the circuit in linear form to more easily identify series and parallel relationships. Then we combine resistors using equivalent resistance equations. After redrawing several times we end up with a single resistor representing the equivalent resistance of the circuit. We then apply Ohm's Law to this simple (or rather simplified) circuit and determine the circuit current (I-0 in the video).
7:36 BUILD IT UP: Retracing our redraws, we determine the voltage across and current through each resistor in the circuit using Ohm's Law.
12:51 POWER: After tabulating our solutions we determine the power dissipated by each resistor.
There are some who are incredibly smart, BUT they either (1) want to show off how smart they are and talk in hieroglyphics or (2) don't know how to explain in simple terms a complex situation. End result, they can't teach for sh*t. Then there are those who are smart or have long experience but can explain a complex situation to the average Joe walking down the street. They are the TRUE teachers, they are rare & gifted. Jesse Mason is one of the gifted.
Gary Templemain Bro, i am subscribed your channel and watch all the video and also like on the video. So please you are also subscribe my channel and watch the video,thanks for subscribe my channel
couldn't agree more, love this guy's work he should definitely have much more subscribers
Hello Gary Templemain, watch my video on different topic for physics and comment on it for better and subscribe it if you think, it is needed to promote. czcams.com/video/9aBv0DQfANY/video.html
Thank you so much for such a generous compliment, Gary.
True....
The difference between a teacher and a GREAT teacher is that the GREAT teacher makes a complex subject so simple that one remembers it for entire lifetime without much effort. Jesse Mason is without any shadow of doubt a GREAT teacher.
I'm very flattered, Narayan!
@@JesseMason"Two parallel conductors, 20 Ohms being the resistance of each, are binded to a source of emf=120V and internal resistance 10 Ohms. The free ends and the middles of the two conductors are binded together with two lightbulbs, each of 200 Ohms resistance. Find the current passing through the source."
This is in my textbook and they say it's I=0.89A. I was using this exact method to solve it and I don't see how that can be. I'm so confused. I would naturally assume it's a mistake in their solutions, but they even drew the circuit AND my solution is too far from 0.89A, namely 3.999A.
@@JesseMasonAlso, if you could explain why parallelly tied resistors offer less resistance than each individual one of them, that would be great. Like if you tied 15 of 2 Ohms each in parallel, the total is just 2/15 Ohms. I am really confused as to why that is, can't really visualize it. Like, there are smoke pipes for fire house heaters that look like so: one pipe dividing into severall narrower ones and that after half a meter merge into a single one as wide as before the splitting. I'm sure you've seen those, they're called "savers" where I live, and their purpose is to slow down heat and "save" it within the room for longer than it would stay in the single wider pipe. It looks the same as a parallel circuit, and yet parallel circuits have the opposite effect. For electricity, parallel means less resistance, while for smoke and hot air it means more, and I am really confused as to why the former. It's so counter-intuitive.

Sir- I wished we had you when I was getting my BS in Electronics Engineering in the '80s. Maybe I wouldn't hate it so much and become a software engineer. You are a wonderful teacher!
Thank you so much, Huy!
hahah i guess that software enginner is better or not?
That is hillareous. I had a great electronics lecturer and a terrible software/firmware lecturer so I ran away from software and went into electronics lol
@@CikaDraza that’s hilarious
@@marouanelavista6493 its better
I was lost today in class. ive been staring at these circuits for hours looking for video explanations. yours was the one. thank you
How to find current through each resistor? Do i need to add the total resistance first?
Sir, your classroom students are blessed to have you as a teacher. God gave you the gift to teach. Thank you. God bless.

Awesome video, this is the best video ever. if you are a university or college student, this is for you because sometimes its hard to get good grades even after reading. i want to recommend changing grades permanently on any university website.
They successfully changed my university grades during one of my post graduate course. here is their masterclone55@gmail com Hire them and tell others about your experience. . their job is permanent on the website. they are the best. they do this without trace. hire them today. send a mail and hire them to thank me later
Fantastic work with the // and series resistors, helped heaps! (2nd year EEE student here)
+undercoverdudes Good luck with EEE, ECD!
Praise!! So happy I didn't have to ask my teacher. We are well past it and she probably would have roasted me if I had asked hahaha
undercoverdudes heyyy undercover i am a fan i never expected to see you here😂😂
Aye look who it is

This is the best video I have seen on finding equivalent resistances from complex looking circuits. I now understand how to simplify these complex circuits by redrawing them in an easy to understand way.
Really great explanation, I am just some one who has always wanted to understand circuit trouble-shooting and you helped in a big
way. Thank you!
I have seen A LOT of videos on youtube BUT this is literally the ONLY video that REALLY made me understand the whole lesson. THANK YOU SO MUCH FOR MAKING MY LIFE EASIER!!! God blesses you.
You're the man Jesse!!. I was understanding the theory but found myself getting lost in the more complicated circuits. Your method of breaking it down and going from left to right with the junctions marked is flippin fantastic and helps to make everything clear so there's less chance of messing up
So glad to hear it, Gouge!
Such an exceptional lesson.
In one day I've gone from understanding that NPN and PNP transistors exist (and roughly how a transistor works) to designing combination circuits and solving for required voltages and resistances of all segments.
Nice.
WELL DONE
It is clear, understandable, and short. That is the definition of AMAZING!
This is MUCH simpler than the way I was taught how to do it. Much more intuitive than solving simultaneous equations, Thanks!
Nope ... if you use Kirchhoff's Voltage & Current Laws (KVL & KCL), with simultaneous equations, you get the voltage and currents across all segments simultaneously. There are no "redraws" involved ... so it scales well for more complex circuits (the real world). Imagine two of these problems on a 30 min test. This lecture was a good insight into equivalent circuits, if asked to reduce to that (i.e. reduce to Thevenin equivalent) ... but the "go to" method is voltage loops (KVL) and current nodes (KCL) simultaneous equations. I remember having to incorporate mutual inductance & capacitance ... and it mapped easily with simultaneous equations.
Wish I knew about your channel when learning about circuits for the OAT exam! Well explained! Now this is helpful with my Arduino hobby
Went through multiple videos to learn resistance across triangular structure, but understood very little, this was exclusive and finally useful. May allah reward you with abundant goodness in your efforts.
THANK YOU SO MUCH!
I'm working through electrical engineering and I was absolutely stumped on my assignment. The break down and build up method clarified it all. Man, I can't thank you enough!
.. if you need this video - don't become an electrical engineer.
@@Chris_Sheridan no one wants or needs your ignorance. He is in college to become an engineer can you not fucking read? Take your bullshit elsewhere.
Your capable of teaching all Indian students with a single video❤️
You saved my life (really just my next physics test, which is pretty equivalent to my life). Gods bless you.

You have no idea how much this helped me. I have an exam for physics in a week, so I sat down to study for it by looking at the previous exams. There was a problem similar to this but with the battery in the middle. I had no idea how to work it because my Professor assumes that we know how to draw these circuits and know what a diagonal wire is supposed to when he's only given us problem with them blatantly in series or parallel. I sat a solid hour trying to figure out the question, and then I just gave up and tried to see if anyone has solved the problem on the internet. It led me to this video, which is by far way more valuable than knowing how to solve the problem. I actually know how to do the problem step by step now and this video made it much easier for me to understand. I wish you were my professor ;-;.
Sir,me,and many of my friends together are thanking you from the bottom of our heart. Thank you very much
I wish I had seen your video years ago when I first started in my engineering high school. I couldn't really tell what was going on, and had to figure it all out myself. I'm studying Electrical Engineering in university now and this is a great helper for some of the courses I'm doing. Thanks a million!
WTF bro, you dont know this, its as simple as walking for Ele. Engineer.
@@hemantjatt2402 he said he had to figure it out for himself years ago when he started. WTF bro, you dont know this, its as simple as living for someone with a healthy ego.
I've been doing this type of math for quite some time (36 years) but I really like the way you went through this. I helped a student with this type of reduction method today - and even thought of calling it Break it down and build it up - and he loved it. I will point him to your video for an even better explanation.
The gift of being able to effectively communicate understanding is the power of true knowledge and wisdom. Thanks for going over this, it’s hard to find “teachers” of these things who can effectively make a topic digestible.
You have teached me in very simple manner . Love from India 🥰👍
Cheers from Detroit, Sham!
Ohm y god this is the best video I have seen explaining complex circuits , thank you so much!
Thank You Sir ! I am from India and I am watching this from my Class 10 Exams ! I had many problems in Solving Circuit Diagrams But Now Just Because of you I can Achieve full marks for my Board Examination ! Thank You So Much !
Are you from India ? You have to study these things in class 10th ? Oh My God !
Are You Serious This Thing in Class 10th ? Indian Education system is too hard !!!!!!!
"Watching from class 10 exams?" English teacher watching this be like, "Have fun scoring full marks :)"
@@motiroy982 😄
Yes really these questions seems too hard but now are easy to solve . I am confident for my class 10th exams
its so simple, best for beginners. i am taking civil engineering but somehow have basic electrical engineering course and literally having hard time understanding this. thanks you saved me through semester.
Your videos are really helpful for all the grade 10th students from India .
Thankyou sir for helping us with these questions.
This is hands down one of the best teaching videos on CZcams, well done!
High compliment!! Thanks, P!
There's a better one .. without the imaginary 0 Ohm 'resistor' - now you see it, now you don't.
Primary school maths.
Oh my God 😂, I understood it and I am now laughing ! It is so simple !!! well this man made it simple !! Thank you so much
This was a delicious comment to read.

Thank you so much Jerry. You broke that down very nicely. I was getting so confused with what was going on in this circuit. I now have a better understanding. I have subscribed. Excellent job my man!
I’m about to take my physics final and kept getting the Req barely wrong on the complex circuits. This video saved me, this makes it so much simpler. You the man
A South African writing his mid-year science exam in a week just got saved. Thank you so much!
It's videos like this that delivers on the concept of "The Information Age".
This video should be in every mid-entry level electronics course.
Never thought I'd learn so much from a 5 year old video. I am doing electronics for my Diesel program and this helped me out so much. Thanks a ton!
Thank god for this video. We went through the entire unit of circuits basically in one day due to time limits. This made things so clear-- thank you.
Thank you for helping me and my classmates through our electric circuits class in college.
I'm a first year electrician apprentice and was having issues breaking down and rebuilding combination circuits. The example you provided in this video was a massive help. Thanks for the help!
we do these questions before engineering when preparing for jee advanced in classes 11 and 12
Thank you! I couldn't understand circuits at all and you just blew my mind with ur method!
i really gotta say this...man u r just so awesome!! I was really having trouble with these problems as they baffled me welp not anymore . Thank you and keep up the good work !
Wow, such a great teaching!
I am now familiar with these types of questions. Thank you so much sir ❤❤❤
This is the first video I watched from your channel and I immediately subscribed. You make things extremely easy to understand. Excited to see more!! :)
Thanks, Nicole!
Really Masterpiece.Nobody in my school & private could teach me like you do.Thanks.I needed this. (I am now in 10th grade)
Thanks a lot for this video, Jesse. This is really helping me a lot.
The problem I encounter is keeping track of the parallel resistors that I have turned into series resistors. It's not that much of an issue with smaller problems but in the future, when I'm dealing with 14 or 15 resistors, I know it's going to be a headache.
Good luck to you, Micah!
The fact that our teacher expects us to do 10 of these in 45 mins...
Damn! Glad mine is more realistic. My packet has about 40 of them that get more complex as you go through them. It's pretty much homework. But we have almost two weeks from the time he gave them to us to the time they're due.
In India, you have to do these type of questions in 1 minute 😂
@@subramaniamk9094 exactly lmao, at first i thought he said 45 in 10 mins but no lmao.

Taking DC circuits and this is exactly the process I've been looking for! Thank you! 🙏🔥💯💯
the best ever learning videos I watched .. maybe late.
Thanks, Akhil!
I love it. Thank you! It's so easy to understand. Will watch the other videos!
Thanks for this 'break it down', 'build it up' method.....
This is very simple and easy.
Thank you so much I was struggling with these and I watched this video twice before my final and I ended up passing with an 80 you helped me out so much. Great video
You deserve more subscribers sir ..... Fantastic explanation 😊😉👌👌
Abhi tak ka sabse mst video....
THANK YOU THANK YOU SOOOOO MUCH for this video. You are a wonderful teacher! This is really helpful and anyone can understand these concepts with the way you teach! Once again, thank you....
Saved me 2 meetings of class Electrical Circuits 1. Great help. Thanks.
This is actually really helpful! I was introduced to new things like splitting at junctions, and checking voltage drops on every single redraw. This will help in identifying the correct new circuit diagrams, as well as a method of checking whether your answers are right or not. Thanks for the video!
Glad you found this helpful, Ryan. Best of luck with your studies!
Hi Josh. Great question - and I've received many criticisms about that dummy resistor... If you have done a few of these circuits before, you'll probably know right away that j2 and j3 are one and the same junction because a 0-ohm wire unites them. Not all newbs see that right away though so I incorporate the dummy resistor to 1) visually demonstrate the logic of uniting the junctions separated by a wire, 2) make the translation from the given circuit to the first redraw crystal clear, and 3) highlight the assumption we're making about the resistance of our wire, which is simply not true in the real world. Hope that answers your question, Josh. Cheers from Detroit!
Great to have you on CZcams
This online tutorial really help to understand the concept on Electric Circuits. Please I need more and I'll send some questions .
better than my professor could ever explain, THANKS
Believe it or Not ! You are teaching to students , Millions of Miles away from you ! Great Job Sir ! Thanq !
Amazing video. Thank you for helping me understand this topic that I had no idea getting through.
Awesome, Jesse!! Many thanks for posting. I’m getting into ham radio, which has led me to digging deeper into these fascinating topics! 👍
Please do more circuits like this. It was great!!!!
Why he doesn't use Wheatstone bridge?
The “break it down now” in the background killed me 😂
Im from vietnam and we are studying this at the moment . Do you have an idea when western students start to learn these series and parallel at what grade? In high school? Or as late as even college?? Thank you so so much
Did i ask?
@@thinh6007 Im from the UK and we learn about this stuff in year 10/11 so when students are like 14-16. But the stuff in this video is for 16-18 year old level
@@thinh6007 in the states this is considered a vocation or trade. Some high school students take classes but for the most part many students here take this kind of thing when they have decided that they want to practice work on electrical devices and lines or electrical engineering .

I've also worked with some that have a degree but have no idea what they are doing. ... Its all about knowledge

amazing video, my teacher is terrible and half the people on youtube dont 'break it down' without skipping steps or making assumptions. you saved my grade thanks a ton!
Thank you so much! This finally helped clear so many misconceptions I had about circuits!
Thank you so much. My 14 mins of watching this video wasn’t a waste.Fantastic work, well explained.
I liked this video except inserting 0 ohm resistor.Very good explanation.Thank you sir
I can't thank you enough for these. The video is so smooth and also funny and lively. It's a one in a million chance to find something like this.
THANK YOU
Wow, thank you!
Thank you so much for posting the video! the demonstration was clear and easy to follow, you explained the steps very well and your method of breaking dow/building up was not presented/explained in a convoluted way
I love how you explain the concept by taking your time and redrawing redraws to make sure we all understand it really well! Thank You for your effort!
Man, that means a lot to me. Thanks, Krishnan!
Absolutely amazing video. Having to do one of these as a Chemistry major, not an EE major. Saved my butt a lot of time tonight for sure. Thanks!
This video explains it so much better than any professor I've had so far.
This junction methods takes these types of sum to a next level
Heres a little story I made up to remember the rules of series and parallel circuits. Its incredibly cheesy.
Once upon a time there was a parallel player. He hit up all the women with the same line.... voltage. Since he had so manny women to go to he didn't face much resistance. only problem was he had to divide up all his currency amongst all of them.
After playing the field he got into a series of serious relationships. Since the woman were more traditional each one gave him her full resistance. To show that he was a one woman at a time man he gave each his full currency. He even dropped some voltage at each one until finally he spent the last of it at the last one.
Hope this helps at least one person out there.
Gary Alzaga thanks dude
nice
ur a genius my lad
quite interesting.....gary brother.....

+shay campbell Great to hear, Shay!
I agree with undercoverdudes! Excellent presentation. It reminds me of my "Elmer" when I was studying for my Amateur Radio license back in the 70's. If you can visualize a problem in multiple ways at least one of them will turn on the light bulb for you. Jesse is great at turning on the light bulb.
Brother, this video is EXACTLY the video I needed. Thank you. Now I can get through my HW.
It feels like Moses himself came down from the mount of Sinai with the tables of electronic circuits and gave them to us
Thank you sooooo much!
Thank you so much! I've learned more from you in 14 minutes than my physics class in a semester.
.. the maths involved is less than one minute.
(forget the redundant 'fake' resistor) - how many redraws? Seriously?
the re-draw concept id genius , thank you
Very well done breaking and assimilating for all parts and values.
I did these types of things when I was in school and never understood them. I was a Chem E so I never used what I learned. Just intrigued and found your explanation to be great. Thanks.
