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

A

0.16J

B

0.32J

C

0.64J

D

1.28J

Text Solution

Verified by Experts

The correct Answer is:
B
Heat produced in the resistor =energy strored in capacitor
`=1/2 CV^(2)=1/2 4xx10^(-6) xx(400)^(2)=0.32 J`
