Nodal Analysis Supernode Example Problem

This tutorial works though a nodal analysis supernode example problem. In this practice problem, we have three unknown node voltages and three power sources. Based on where we drew our ground, two of the unknown nodes are connected with a voltage source, so we can use supernode analysis to solve the problem.

This video is part of a full free course on electric circuits. The course covers DC circuits, circuit laws, current & voltage sources, series & parallel resistors, nodal analysis, mesh analysis, and AC circuits.

Why do I find you the night before my exam

[muradtashkandi]

Very informative video, was struggling a bit with understanding supernodes, but this helped a lot!

small side node, at 6:44, when finding VA, you plugged in the whole equation to find Va after we got Vc, when you could've simply used Va = Vc + 3 (Which we found earlier). I know it's nothing big but I just wanted to point it out haha.

Excellent detailed video but it should also be noted that this can be solved super fast with super position.

[gokucrafter]

With a little bit of observation, we can solve really fast by choosing nodes, by choosing the ref at the mínus terminal of the 2V voltage, node a at the intersection of 2 amp source, 3 ohm, 1 ohm branches, node B at the lowest part of the circuits.

@ 5:25, why is vb 2 volts higher than vc? pls explain

[rfb]

Could you please please please explain the superposition theorem of electric circuits?
I’ve been following along with your videos since the beginning of the semester and they’ve been a huge help.
Thank you so much 😊

hello i have some question how did you get the 1.5 + 0.75 +Vc + 1.5 + 0.25 Vc? in 5:35

[marklambino]

is it possible to use Cramer's rule in this particular problem

[sahidamardhi]

A very detailed explanation! thanks. But if I may ask, if the voltage source is flipped to - +, does it affect the equation of the voltage between vb and vc?

[sajanasathira]

why did you choose point C in random point instead of a junction please someone explain

[saminsamad]

Well I think the math could have been much simpler if we wrote 2 instead of I1+I3 on the second equation, since we already have that equation also I checked the answer it remains the same so I guess we could do that

Sir, my lecturer teach me to use kcl and kvl at super node is it correct? I'm confuse.

[isamuraixx]

What if there’s a supernode between 3 voltage or nodes, what will be the super node equation?
