Question

Assertion : When an uncharged capacitor is charged by a battery only 50% of the energy supplied is stored in the capacitor. Reason : Rest 50% is lost.

Answer 1

When a uncharged capacitor is charged by a battery only, only 50 percent of the energy is stored in it. The reason for this is :

When the capacitor is charged, due to heat losses and transmission inefficiency, nearly 50 percent of the transmitted energy is lost.

The capacitor is a device which is used to store large amounts of charge. The charge is given by the capacitance multiplied by potential difference. Thus, more the capacitance or potential difference more will be the charge stored in the capacitor.
