Electrical Engineering: Ch 4: Circuit Theorems (19 of 32) Norton's Theorem Example 1

In this video I will find the Norton equivalent circuit of a circuit with a 2amp source with 8V voltage source and 2 resistors.

Next video in this series can be seen at:

You are an excellent teacher. No one can teach all these topics better. I love the way you present these complex techniques simply. I've been following all your videos. I appreciate you. I want you to minimize the way the board is covered during lectures. I don't know how you can do that but I want the board to be visible at all times.

[Jazzid]

Perfect! Among my favorite online lectures! Thank you!

I think at 2:40 it would be easier to transform the 8V and 8 ohm to a 1 amp parallel to 8 ohm. Than there would be only one current source of 3 amp!

[Festus]

@1:38 you say the Norton resistance is the "resistance between A and B"... WHY?. If the circuit is open between A and B the resistance is infinity.

Hey Michel, I really appreciate your lectures, and have been watching them for a little over a year now. I was wondering, when you disconnected a current source and replaced it with an open source, what if there happened to be a resistor that ceased to allow current to run through it? How would that affect finding Rth? Thanks!

where was I to find a good teacher like you😭😭😭

[ladyphoenix]

So well presented. Thank you so much.

I am having a hard time understanding why the I1 is equal to 2 Amps. i get that there is a current source there that says 2 amps but what about the 8 ohm resistor and 8v voltage source?

[GroovePG]

Why did we add the 16ohm and 8 ohm resistor if they were in parallel?

[ReagueOfRegends]

Out of curiosity, if we had a wire which began between the 16 Ohm resistor and the end-point A which ran down and connected to the end-point B branch, then the 8 Ohm and 16 Ohm resistors would be in parallel, correct? This seems to be something a lot of beginners, including myself, struggle with. There are so many definitions of parallel resistance that seem inconsistent. I usually go by "if the current splits between multiple resistors and end up back on the same branch then they are in parallel".

Hi Michel, wondering what will be the value of Load R., I think you did not find that...

[lintugogoi]

why does current I1 flow through only 8 ohm resistance, but not through 16ohm? sir please explain...

[gabrieldennery]

How do you know I-1 of the Mesh Analysis is equal to 2 Amps? It does not appear to account for the I-2 traveling in the opposite direction through the 8 V and 8 R elements. Someone please clarify this point for me.

[koko-ozjf]

just curios what would be the Rth if there was another resistor after the 2A

A video on Thermodynamik, Gas - Dampf. Feuchte Luft is needed. Best Regards KQKR Kristian

[theson]

im so confuse . at lesson 16, we have the same situation by they are parallel. why are these resistor are in series now ? ???

[emmanuelapuamadi]

Please sir how did the voltage source(8v) goes to zero? I’m confused

[ghassanarnouk]

Great explanations!
But I have a question: when you are writing the equation in the loop 2, doesn't the equation have to be 8 + (8)(i2 - i1) + 16(i2) = 0 which would give a current of 1/3 Amp

[quratulain]

In this case, can we use Thevenin theorem?

[jacobnatalinogomes]

????If We assume RL is 1ohm
Than equation Must be IL=(1/1+24)*1
