In the circuit shown the cells are ideal & of equal e.m.f., the capacitance of the capacitor is C & 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 capacitor
B) half of the energy finally stored in the capacitor
C) twice the energy finally stored in the capacitor
D) 4 times the energy finally stored in the capacitor.
Correct Answer: D
