[damodark]

Superb explanation. .like spoon feeding...thanku so much....

[mikhileshmhirphode]

According to explanation ....
acts as source and delivers the power i.e.
Power=P=-(8x2)= --16W

[narendermatta]

-16w bcz current leaving from +ve terminal acts as source

[adityajayswal]

great education by great platform neso academy is the best

[rohitsharma-dbuf]

Will you please explain the point of assuming load in place of source in detail that you mentioned just before the examples

[aneetakushwaha]

Thanku so much sir. concept about the power is now clear. hw ans is -16 W and its act like a source

[nisanuryıldırım-ei]

This channel is truly amazing. thank you for your effort <3

[gokulkrishnan]

Sir i didnt understand the last two examples..can u pls explain clearly why we are putting negative sign for current entering positive terminal

[nazninhaque]

plz upload a playlist of electromagnetic theory and communication theory as well

[techinfosupport]

-16w acts as a source and power will be delivered

[wajahatsohail]

-16 watts i enters in to the -ve terminal from Outside . Will Deliver power and act as a source.

[ragnarok]

The only problem with your videos is low sound. Content is excellent but due to low sound, we always have to rely on speaker/ earphones

[sanket]

Just redraw the diagram you will get the answer correctly.
Leaving +ve - 16W
Acting as a source

[rasagnapothu]

Sir, need one clear explanation.You have said that current is the direction of positive charge direction then the current is due to the movement of positive charges right but you are telling it is due to negative charge how is it possible

[anubhavshukla]

THE ANSWER OF THE HOMEWORK PROBLEM IS -16W AND IT ACTS AS A SOURCE.

[sandeeptiwari]

Sir I would not understand it well.... please answered me how can I understand it??😔😔😔

[srimangainathan.t.kece-]

i have one doubt, we knew that current always flows from higher potential to lower potential.Then why when u explain the source, in source why current flows from lower potential to higher potential.

[manishkumarkmmani]

Sir my question is if a current flows from point a to b of potential Va and Vb then amount of electrical energy should be E=q(Va-Vb) but practically because of collision energy is lost in the form of heat then total electrical energy should be sum of thermal dissipation and used electrical energy but you are saying formula of themal energy is qv and joule's heating law also states the same then we get electric energy and thermal energy equal if we add both it will be greater than supplied energy
this is what came to my thought please answer me and correct me I am waiting for the right answer

[ItsPankajYeole]

last problem(answer)-power-(-16) it is acting as a source..

[prabhakardas]

-16 watt, and it is delivering power, acts as
