Questions
Calculate the amount of energy released on discharging a capacitor which has a potential difference of 200 V across its plates and 0.1 C charge is stored in it.
detailed solution
Correct option is B
Here, V = 200, q = 0.1 C.Energy stored,U=12qV=12×0.1×200=10JWhen the capacitor is discharged, it releases the same amount of energy i.e., 10 J.Talk to our academic expert!
