Can you do this problem elaborately? It is still confusing how you wrote the answer as like that

[@Zer0-0]

Wait a second, how are you writing backwards?

[@silverback5352]

the video is mirrored, hes writing normally

[@aminyusop2212]

Why can't we assume that the unknown current is going inward? I mean why must outward?

[@robertllopet5357]

all currents in the super-node go outward, but as current source is inward it is -2Amp

How does V2 = 40/1+j7?

[@robertllopet5357]

answer is correct v2=40/(1+j7) = -0.8+j5.6 and v3=40/(1+j7)+j4=-0.8+9.6i

Sir ,you teach really great , I love watching your videos and I just subscribed,can you please make videos on ac power numericals (reactive,comlex,active power)

i guess Im randomly asking but does anybody know a tool to log back into an Instagram account? I was stupid forgot the login password. I would appreciate any help you can offer me!

@Landry Izaiah Instablaster :)

[@landryizaiah2788]

@Xander Kristopher Thanks for your reply. I found the site through google and I'm trying it out atm. Takes a while so I will reply here later with my results.

[@landryizaiah2788]

@Xander Kristopher it worked and I finally got access to my account again. I'm so happy! Thank you so much you saved my account :D

[@xanderkristopher1412]

@Landry Izaiah no problem :D

[@ramyasri7899]

Sir tell me what we have to do if w value was not given
