A 4 `mu`F capacitor is charged to 400 V and then its plates are joined through a resistance of 1 K `Omega`. The heat produced in the resistance is

A

0.16 J

B

0.32 J

C

0.64 J

D

1.28 J

Text Solution

Verified by Experts

The correct Answer is:
B, C
The energy stored in capacitor is converted into heat
` U = H = (1)/(2) CV^(2) = (1)/(2) xx 4 xx 10^(6) xx (400)^(2) = 0.32 J `
