A 2`mu`F condenser is charged to 500 V and then the plates are joined through a resistance. The heat produced in the resistance (in joule) is

A

0.10 J

B

0.15 J

C

0.25 J

D

0.30 J

Text Solution

Verified by Experts

The correct Answer is:
( c)

Heat produced in the resistance,
`H = 1/2CV^(2) = 1/2 xx 2 xx 10^(-6) xx 500 = 0.25 J`
