Why do I find you the night before my exam

[@murray9929]

Me too!

[@amithbkumar495]

Haa me too. My electrical exam tomorrow 😂

[@coldjokerz]

Same

[@graceokeefe8900]

Bc I search for him night before my exam

[@qemmm11]

Super easy 😊

[@muradtashkandi5083]

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.

YEAH

[@safwanshahriar4108]

Excellent. Commenting for algorithm

[@Engineer4Free]

Thanks! 🙌!

[@gokucrafter9456]

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.

[@josephguida5432]

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

[@wondersarfo9201]

How ?

[@HipHoplyricalanalysis]

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

[@sicamasocima6045]

because its voltage rise from negative to positive .

[@MelkamuWako-f3v]

best presentation, i love it

[@EngineerAbhay-28]

Nice explanation

[@Engineer4Free]

Thanks! 🙌

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 😊

[@saminsamad4346]

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

[@sajanasathira]

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

[@arvincimafranca1750]

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

[@markdennisobumani2741]

he divided the whole equation by 4 to leave only Va on the left side

[@bryanmaeobea]

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

[@Nour-em9qg]

Thanks so much

[@Engineer4Free]

You're welcome! Thanks for watching =)

[@isamuraixx3441]

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

[@marklambino6887]

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

[@gamma-qh5yv]

yes you can I tested it

[@harryson2841]

Thank you very much!

[@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?

[@sanketburji1505]

yep it does just reverse the signs like vb-vc= -2V

[@qemmm11]

Yes

[@muhangianold4431]

Thanks

[@adityarana3722]

Thank you sir

[@lmao2908]

@ 4:32 can we write I1+I3 as 2 ?

[@saminsamad4346]

yes you can makes the math way shorter, probably you will save 2 to 3 mins in exam which is a plus

[@mdrubelmia7710]

well i understand thiss video

[@Engineer4Free]

Glad to hear it!! Full circuits playlist is down in the description 😁

اريد ان احصل على نسخه مترجمه للغة العربية

[@sumisap7444]

Great

[@NahBruh1232]

how the fuck are u guys understanding this?

[@burhanulaziz5678]

thanks
