☑️25 - Series and Parallel Capacitors Part 1 (Intro + Solved Problems)
In this lesson, we are going to learn how to combine capacitors in series and in parallel.
This lesson is the first part of two.
We shall focus on introduction to series and parallel capacitors as well as solving couple of examples.
Capacitors in Parallel
Ceq = C1 + C2, Equivalent capacitance formula in parallel
V = V1 = V2, Same voltage across capacitor
Q = Q1 + Q2, difference charge on each capacitor, hence total charge Q = Q1+Q2,
Capacitors in Series
1/Ceq = 1/C1 + 1/C2, Equivalent capacitance formula in series
V = V1 + V2, Source voltage = sum of voltage drops
Q = Q1 = Q2, same charge in all capacitors
00:00 - Parallel Capacitors
05:06 - Series Capacitors
10:13 - Question 1
13:38 - Question 2
18:01 - Question 3

you are so wrong. to determine the order of a differential equation the equation should be in polynomial form as far as derivatives are concerned . otherwise order is not define. you 1st equation is trigonometric not polynomial then order is not define. same in 4th one.
I like your approach to teaching bro
Aww thank you very much
Guy God bless u soo much .I appreciate u from Ghana
Aww great thanks so much. Please which campus do you watch me from?
Thank you Sir! I am from Sri Lanka! I am also conducting Educational youtube channel Sir☺
Aww great. Good luck

Why do we have 3 and 8 when the inequality is not (inclusive)>= or<= ?
Yes, we need to include 3 and 8, however because they are not inclusive, we represent them by an open set (open circle)
I love the teaching
Thank you very much
It seems I'm confused with the example two😢😢
Really, please what's the confusion
Very useful video for grade 11th student thanks sir
You are most welcome

Please, What if I want to use matrix?
That's great, you can ask well use matrix
This has really helped me. Excellent job. Keep it up
Thanks so much Betty, Where do you watch me from?
Please how you found lambda with third equation like in the video (10:32)
It's a cubic equation, just punch on your calculator
please do a video on triple integrals in cylindrical/spherical and the regular triple integrals bounded by planes. your videos are the best!
Okay, noted with thanks
Thank you for making this lovely video. I did learn a lot from it 😊
Awww thanks so much
For the first example the mesh 1 how did u get the 4 ohms to have the current of I1 while the 12 ohms the current is (I1-I2)
It's simply because 12 ohms is in the middle branch, and in the middle branch, the total current is as a results of i1 and i2. Since i2 oppose i1 The total current is i1-i2
Cool I solved this with my teacher yesterday 😊
Great, 💯
❤
Bro you didn’t treat the applications of first order ODE
Do u determine the direction of your nortorn current? Or it is your decision
You decide however you want to do it.
Please l am an online math tutor like you. Would you mind telling me what kind of iPad or computer tech you are using to create this videos. For truth to be told, it's awesome.
Thanks so much for your comment. I use a graphics table (Vson)

But how does it equal back up to 128 that's what I can't understand bro and exam is Monday💔
Please come again with your question, which 128 are you talking about. Kindly specify the time in the video
1:28
Because you said 2³+⁴ is equal to 7 which is going to become 2⁷ then you said that's gonna equal to 128
So what I don't understand is how did you get the 128 after the 2⁷=
So please do explain
what is the name of the software that is used to draw this specefic circuit in the video ?
Smoothdraw
@@SkanCityAcademy_SirJohn wow! that was so quick ! thanks but i meant the circuit itself , where can i draw circuits like that one ? thanks again
@mustafaz247 oh okay. I took it from a textbook.
@@SkanCityAcademy_SirJohn aha alright , thanks a lot , i really appreciate it !
@mustafaz247 you are most welcome
Sir when you will start lectures on basics of dynamics
I don't really know, but I don't think it would take too long a time
Hello sir, in the very first problem, how are the resistors of 2 ohm and 8 ohm in parallel? Aren't there a dependant current between them?
no please, 2 and 8 are in parallel kindly check the two elements, they are connected to the same node. Again you can go round a loop, containing only 2 and 8 ohms resistors, hence they are in parallel.
@@SkanCityAcademy_SirJohn So sir, the dependant current source in between those resistors don't have any role right?
@FaiyazBinYousuf they have, but not at the point of finding the combination of the two resistors
Please, for the last question, why is the set closed
The set is closed because it contains it's limit point, which in this case is 1
Please, for the last question, why is the set closed
Please, for the last question, why is the set closed

Can you please come again

this guy most definitely knows the way
Thanks so much for watching
I=V/Rt=42/18 (12+6) how could be 18 ?These are parallel of seires?
I don't really get your question, but the most important thing is, because of the open circuit, there will be no current in 3 ohms, so the current in 12 and 6 is same, which means 12+6 is 18 Hence I = 42/18 = 21/9
Thanks bro
You are most welcome
Please how is it 2000
Fraction left was 1/4 Hence to find the amount of money he took from the bank. It's going to be If 1/4 = 500, then 1 = x Then we say x = (1*500)/1/4 = (500*4)/1 = 2000
