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.
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 😊
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
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.
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?

Why do I find you the night before my exam
Me too!
Haa me too. My electrical exam tomorrow 😂
Same
Bc I search for him night before my exam
Super easy 😊

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

Sir, my lecturer teach me to use kcl and kvl at super node is it correct? I'm confuse.
why did you choose point C in random point instead of a junction please someone explain
What if there’s a supernode between 3 voltage or nodes, what will be the super node equation?
Excellent. Commenting for algorithm
Thanks! 🙌!
@ 5:25 , why is vb 2 volts higher than vc? pls explain
because its voltage rise from negative to positive .
hello i have some question how did you get the 1.5 + 0.75 +Vc + 1.5 + 0.25 Vc? in 5:35
he divided the whole equation by 4 to leave only Va on the left side
is it possible to use Cramer's rule in this particular problem
yes you can I tested it
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?
yep it does just reverse the signs
like vb-vc= -2V
Yes
Nice explanation
Thanks! 🙌
Thanks so much
You're welcome! Thanks for watching =)
Thank you very much!
@ 4:32 can we write I1+I3 as 2 ?
yes you can makes the math way shorter, probably you will save 2 to 3 mins in exam which is a plus
Thanks
Thank you sir
well i understand thiss video
Glad to hear it!! Full circuits playlist is down in the description 😁
Great

how the fuck are u guys understanding this?
thanks
