If an uncharged capacitor is charged by connecting it with an ideal battery and a resistance R as shown. Then heat generated in resistor R by the time capacitor stores energy `(1)/(8) CV^(2)` is :

Options

A. `(1)/(4) CV^(2)`
B. `(3)/(8) CV^(2)`
C. `(1)/(2) CV^(2)`
D. zero

Answer

B

Explanation

`Delta U = (1)/(8) CV^(2)`
and Workdone by the battery
`:.` Heat generated `= (3CV^(2))/(8)`.
