Question

The figure shows a circuit with a source of emf epsilon, a resistor R, a capacitor C, and a switch. Initially the switch is open, no current flows in the circuit,and the capacitor is uncharged. (Figure 1) At time t = 0 the switch is closed, current begins to flow, and the capacitor begins to charge. Which of the following statements about the power supplied by the source of emf is correct? it is proportional to (e-t/RC)2 = e-2T/RC it is proportional to e-t/RC it is proportional to (1 - e-t/RC)2 it is proportional to 1 - e-t/RC none of the above is correct

Explanation / Answer

option C is correct as power is directly proportional to square of voltage.
