Consider the situation shown in the figure. The switch S is initial open and the circuit is at steady state. Now the switch S is closed. Then the total charge flown from X to Y is aCV, work done by battery is $bCV^{2}$ .\\

$b =$ $____$ .

Answer:

0.33

Solution:

Work done by the battery = $V \times$ charge it supplies $= \frac{1}{3} C V^{2}$ .

$b = \frac{1}{3} \approx 0.33$ .
