Question 554: Electrostatics & Capacitance

Question

A battery is used to charge a parallel plate capacitor till the potential difference between the plates becomes equal to the e.m.f. of the battery. The ratio of the energy stored int he capacitor to the work done by the battery will be

Accepted Answer

Energy stored in the capacitor $$\mathrm{U}=\frac{1}{2} q \mathrm{~V}$$
Work done by the battery $$\mathrm{W}=\mathrm{qV}$$
$$	herefore \frac{\mathrm{U}}{\mathrm{W}}=\frac{1}{2}$$
