The second in the series exploring electronics. We dig a bit deeper into ohms law. If you missed it, start with episode #1: • Electronics: Lesson 1 ...
Leo I think your paced, un pretentious style is perfect. No intellectual snobbery just a genuine desire to inspire and teach. Thank You, Mark in England, I’m engrossed!
At nearly eighty years of age I am delighted to have found your channel. In the background I've been digging here and there and so far so good. No other channel made these concepts as clear, not slamming them, I realise that my own level is that low. Thanks.
Leo! You are an amazing teacher! Your way of conveying electronic concepts separates you from all of the others! PLEASE continue to produce more content like this!
I am much further along in my electronic studies and I am genuinely excited to see your explanations on all future concepts. Even though I know all of the things you have mentioned in this series, you explain them with a very unique perspective that makes me look at these components in a different light. Thank you for your excellent videos for all of us aspiring electrical engineers.
This is the best teaching I've seen in this potentially boring subject. Infanantaly better than sloppily drawn pictures. I don't know if one can make a dollar writing college text books today but if you did I would want one.
Hi Leo, I found you from researching wire wrapping. I'm really enjoying your videos and your english. I will send you plenty of comments as I explore your rich and well made content. Good on you for now. Catch you later, Michael
Excellent dive into dividers... basic and truly thorough that's tough to do at the same time in electronics. I love your style of teaching this difficult topic. I myself am just a guy who has no formal higher education, yet I truly believe I can learn anything I choose to pursue. Whether Self learned or with a little guidance and assistance in knowing where to go next or what to avoid. The latter being the preferred method, but there is something to say for having taken the long scenic route. You really learn whatever it is you strive to learn. All of it, the mistakes, the pointless tedious time wasters, and eventually the best method of reaching any desired end. So really, if you don't mind the time it takes to learn the topic the first way it truly better, as it gives you the ability to teach the topic to someone else from experience and not from a textbook. Its more fundamental knowledge compared to learned from word of mouth or text in a book of which its origin is unknown... I undertook electronics simply out of curiosity and an attempt to understand this killer in our walls that I knew nothing about. I just jumped in, first with physics and then into circuits and design techniques and everything in between. CZcams has helped a ton, but really, it's so broad a topic that it makes being distracted with pretty lights and loud sounds almost unavoidable. The good ole paperbacked version of the rules to adhere to when working with electricity was much easier to truly learn and stay focused for myself, that is. I've amassed a large stack of notebooks full of notes and circuits over the five or so years I've been at this. It has been a long journey, alone is tough. but that's how I like it. It's how to get the most fulfillment out of anything pursued IMO. Any how Your teaching style is great for my mind, and I look forward to some more difficult aspects of the art being explained through your lens as its quite similar to my own. Our sauces would make a nice goulash together. (Tenacious D) so thanks for the vid and throw more in the bag when you can...
I've been looking for a series like this, that steps outside of the box, great work! In this video, I would have ended by showing the tapping point for the reduced voltage between the two resistors, but I'm sure you'll get to that.
Can’t wait for the third lesson. Can you illustrate some of the theory such as using a multimeter? So I can follow in practical sense such as the various points in a circuit showing say the voltage drop across resistors etc. I find it much easier to remember that than just the theory alone. It’s very cheap to buy a breadboard and components these days. Thanks for the series so far.
awesome! did not know about being able to add up conductance in parallel. I love those little nuggets that make this worth watching even for someone who has been working with electronics for years!
a fun exercise (in my opinion), is practicing calculating equivalent resistance on sample problems. Circuits full of resistors in various patterns, values, etc. and you go through and reduce the circuits down to a single equivalent resistance value.
That was the best way I have seen it explained!! Especially the quick and dirty way to work out the resistance in parallel! Thank you so much. I aim to go through all your tutorials
Great explanation of what the equivalent resistance formula is doing. I've seen several other explanations but yours is the most direct and easiest to remember.
Keep this series going. So much of this information may be covered by other channels but none of the content creators speak American English. I struggle understanding accents and dialects. It becomes hard to learn the material. Through these videos I now understand Ohm's law much more clearly. Thank you for these videos.
So far so good. I wouldn't mind seeing more study on resistors and especially with dividers. I would also like maybe a question at the end with an answer in the next video. I know this is all way too late now but I just thought I'd put it out there in case you continue on with other subjects.
Excellent way of presenting the basic notions. In the preceding video, I found your analogy of the electrons in the wire with ping-pong balls in a tube a very concrete and useful way of presenting the information that helped me refine my understanding and vision of electricity principles. As well, in this video your explanation of the resistances in parallel formula instantly switchd a light on in my mind and it became very concrete and logic. Now, instead of an off-putting formula I have to learn by heart, it is just the simple mathematical expression of the words you used to explain it. Very clear. As a self-taught beginner in electronics, I greatly appreciate the way you share your knowledge and I hope you will continue this série on electronics. On a side note, I enjoy very much the sounds of birds singing in the background in many of your videos! Thank you, your efforts are very much appreciated! 👍
Great videos man, I am 3rd semester mechatronics major in college and it’s really really helpful for me to go back and look at the basics broken down the way you are explaining them. I am great at math but that hurt my overall understanding and you are exactly what I need to get that thorough grasp of the concepts I was punching in my calculator getting a’s on tests but struggling with actually wiring simple circuits. Keep it up just the way you are I love your pace and you have helped me a ton already
Thank you very much for these videos. I’m trying to learn electronics and your intuitive way of explaining it makes it very easy interesting to learn. Maybe showing the electronic components and doing small demonstrations would make it even more interesting and intuitive and facilitate learning. Thank you so much. You have a gift for explaining electronics!!!
Ready for the next Lesson! I really appreciate what you're doing here. I'm a little slow (real talk) when it comes to learning. I had to rewind this video a few times in certain sections because of the vital knowledge. I like that! I want to thank you for making it short and to the points. I know my attention span isn't long as it was 20 years ago but we have this information, technology, and knowledge today easily accessible. In this day we really have to utilize these tools. I'm sure you will have great learning content coming soon. Do what you do man. I was checking out your older videos too. Great job brotha stay Blessed! 👍👌
very nice 😃 The voltage divider is one of the simplest circuits you can think of but also one of the most important - you can use it even to introduce more advanced concepts such as input and output impedance and attenuation right out the bat. I'm gessing the next video is going to be about non-ideal voltage sources and its equivalent internal resistance 🤓🤔
Great job explaining electronics to a beginner Keep up the good work. Please let us know the model and brand when talking about tools and equipment if possible. Thanks.
Regarding slide rules. They are great at enforcing significant figures, and in reality, often times super precise calculations with many decimal places aren't accurate anyways. Those fancy theoretically perfect calculations fail to account for manufacturing tolerances of components, impurities and imperfections in the raw materials, environmental factors, and more. By calculating things less precisely, you're inadvertently accounting for variations due to reality anyways. What good is a calculation to 7 decimal places if the best you can manufacture to is 2 decimal places? So it's ok, and proper, to not use theoretically exact calculations and introduce a bit of rounding (tolerance) to the calculations. Slide rules also teach logarithms, help people visualize the math, help them learn and practice scientific notation, etc. Slide rules need to be brought back into math education for pre-algebra math. They are not hard to learn, you just have to practice, and would make students more intuitive with math later on.
All the basics, thank you! Recalling my school physics classes. So if we develop that idea of a voltage divider, when we want something to have V1 as in R1, we just connect the node parallel to R1, and that's it?
Hi, please help to understand how to read the power rating, its meaning.. like what are meaning of 25S, timeline 2.50 . And many thanks for such awesome teaching 🙏
Hi Leo! Thanks for your efforts. There are tons of information about basic stuff everywhere (books, websites, youtube). So when someone does /yet another "how to solder" video/ he doesn't really add something new and unique to what already exists. And on the other hand, if someone is too lazy even to open a book and read about ohm's law, you shouldn't spend your time to make his homework. I guess, the most valuable thing students can get from experienced engineer is not well-known "facts" about electricity but "methodology" of how to create/repair electronics. So share your experience, tell us about your knowledge and engineering skills and tricks, your way of thinking - this is priceless!
Hard to understand what your talking about because your using formulas without values. Is this a math class? Typical that a person experienced takes for granted the basics. Why does a battery short it self out unless there is a tiny load?
Oh my god what a masterpiece lecture it was , even thousand times way better than my college. Thank you so much sir please continue this series and extend it by adding more creative electronics topics like different equipments how they run and what are they how they work why we use them. Ultimately we are here because your videos crystal clears our basics and we want exactly that. ☺️🤍🤍🤍👌
Completely confused by the end 😂 but your videos are still the best I've seen so far. I agree with some other comments here, adding a physical demo to a lot of this would be awesome! Like you did with the resistors in episode 1. Thanks for the series! (Although it does look like you've stopped it? 🥲)
Leo I think your paced, un pretentious style is perfect. No intellectual snobbery just a genuine desire to inspire and teach. Thank You, Mark in England, I’m engrossed!
Excellent! Look Forward to more episodes!
At nearly eighty years of age I am delighted to have found your channel. In the background I've been digging here and there and so far so good. No other channel made these concepts as clear, not slamming them, I realise that my own level is that low. Thanks.
I am SO glad I found your channel! The way you explain electronics and principles is straightforward and intuitive. Thank you!

Thank you for this great video Leo, I hope the community gives you the support required to keep them coming!

You have the best web site that I've seen for some one trying to learn electronic. I definitely subscribed and hit the like button. Thanks Randy.
excellent content, please keep it coming
I'm glad you're back. You have alot to teach. I can't wait until you start with intermediate stuff.
Thanks Leo. Can i suggest keeping practical demos in each video, ideally using low-tech methods available to younger fans?
I agree, a practical/physical demo, however simple, would be appreciated to cement the significance/application of the concept.
Agreed - showing your circuit and measuring the voltage at different points would back up what you are explaining.
Excellent explanations!!
I've been looking for a series like this, that steps outside of the box, great work! In this video, I would have ended by showing the tapping point for the reduced voltage between the two resistors, but I'm sure you'll get to that.
Fantastic explanations. Thank you and look forward to more lessons.
Awesome! looking forward to quick practice projects
Love it! Slow and smooth “is fast”…. Where were you 7 years ago when I decided to self teach myself electronics 🤓
Can’t wait for the third lesson. Can you illustrate some of the theory such as using a multimeter? So I can follow in practical sense such as the various points in a circuit showing say the voltage drop across resistors etc. I find it much easier to remember that than just the theory alone.

I think you are doing a great job helping people to understand electronics in a much easier way
Awesome. Love the level you target and analogies use.. Looking forward to #3.
Great video. Easy to understand.
awesome! did not know about being able to add up conductance in parallel. I love those little nuggets that make this worth watching even for someone who has been working with electronics for years!

You are the best teacher I have ever come across with electronics I hope you continue the series. Thank you Leo
Leo, thank you for your extreme patience with these lessons!
That was the best way I have seen it explained!! Especially the quick and dirty way to work out the resistance in parallel! Thank you so much. I aim to go through all your tutorials
Great explanation of what the equivalent resistance formula is doing. I've seen several other explanations but yours is the most direct and easiest to remember.
You've got this. I haven't enjoyed basic electronics this much since I first read Forrest Mims' Radio Shack books.
Keep this series going. So much of this information may be covered by other channels but none of the content creators speak American English. I struggle understanding accents and dialects. It becomes hard to learn the material. Through these videos I now understand Ohm's law much more clearly. Thank you for these videos.

Thanks for making these Leo! I really like your style! Can’t wait for capacitors & inductors
Thanks Leo I’ve been learning electronics for a few years now and I always learn a new trick from your videos.
Can't wait for lesson 3
I think that's the best and most understandable course ever watched. Can't wait to the next episode!

Excellent, knew I'd get on board and understand this more than other attempts at getting my head round all this, thank you 👍
Thanks from Brazil. I finally get it
Looking forward for 3rd video too
Great videos man, I am 3rd semester mechatronics major in college and it’s really really helpful for me to go back and look at the basics broken down the way you are explaining them. I am great at math but that hurt my overall understanding and you are exactly what I need to get that thorough grasp of the concepts I was punching in my calculator getting a’s on tests but struggling with actually wiring simple circuits.

Maybe showing the electronic components and doing small demonstrations would make it even more interesting and intuitive and facilitate learning. Thank you so much. You have a gift for explaining electronics!!!
Waiting patiently for your next video.
For reinforcing learning, I would suggest adding some simple questions at the end for viewers to self-answer; maybe with answers in the description.
Ready for the next Lesson! I really appreciate what you're doing here. I'm a little slow (real talk) when it comes to learning.

You nailed my thought process
Very clear explanations
well done! you explain things so anybody can understand

amazing thank you, I’m excited for next lesson!
Excellent! Keep them coming please. Is this series going to be a sort of roadmap explaining how each component behaves or something?
Loved it!
Good stuff, I am going to turn my grandson on to this series. Thanks
These are great please keep explaining how you are the math is always what confused me, and probabky having terrible teachers
very good, thank you
Great!!
Thank you so much
Also I don't know how busy you are but is there any chance you could do a lesson every couple of weeks 😉
All the basics, thank you! Recalling my school physics classes. So if we develop that idea of a voltage divider, when we want something to have V1 as in R1, we just connect the node parallel to R1, and that's it?
Great 😊
Really getting brains 🧠 "clicking" here 😆
Ieo you are very!!! awesome I love being your student continue I gives your constant turnup okay.
Hi, please help to understand how to read the power rating, its meaning.. like what are meaning of 25S, timeline 2.50 . And many thanks for such awesome teaching 🙏
your link takes you to back to this episode, just an FYI.
Thanks! fixed it.

When is lesson 3?
Hi Leo can you do some more examples of this lesson please
😢
Where id you go?
In a circuit that has multiple resistors, such as your two resistor example, why not just use one resistor that equals the value you need versus two?
@leo - time 11:53 that looks like a Tektronix CRO schematic diagram
And so it is! some totally badass electronics designs!
@@leosbagoftricks3732 I used to service the 76xx series in the 80's.. they were ahead of the curve with their designs indeed
L almost don't understand anything,what should l do
😢
Boop
.

☺️🤍🤍🤍👌
Completely confused by the end 😂 but your videos are still the best I've seen so far. I agree with some other comments here, adding a physical demo to a lot of this would be awesome! Like you did with the resistors in episode 1. Thanks for the series! (Although it does look like you've stopped it? 🥲)
