In the circuit shown the cells are ideal and of equal emfs, the capacitance of the capacitor is `C` and the resistance of the resistor is `R`. `X` is first joined to `Y`and then to `Z`. After a long time, the total heat produced in the resistor will be

A

equal to the energy finally stored in the capacity

B

half of the energy finally stored in the capacitor

C

twice the energy finally stored in the capacitor

D

3 times the energy finally stored in the capacitor

Text Solution

Verified by Experts

The correct Answer is:
D
(d) Word done by cell `= 2 q.V`
`= 4 ((1)/(2) q.V)`
`= 4` (energy stored in capacitor)
