Question

A capacitor is charged through a potential difference of 200v. When 0.1C charge is stored in it. How much energy will it release when it is discharged?
​

Answer 1

Explanation:

Correct option is

B

10 J

Here, V=200V,q=0.1C

Energy stored, U=

2

1

qV=

2

1

×0.1×200=10J

When the capacitor is discharged, it releases the same amount of energy i.e., 10J

Answer 2
