In a charged capacitor, the energy is stored in

What fraction of the energy drawn from the charging battery is stored in as capacitor

An uncharged capacitor is connected in series with a resistor and a battery. The charging of the capacitor starts at t=0. The rate at which energy stored in the capacitor:-

Assertion: When an uncharged capacitor is connected across a battery, half the work done by the battery is stored as electric potential energy inside the capacitor and remaining half is dissipated in the form of heat. Reason: When an uncharged capacitor is connected across the battery then potential difference between the plates of capacitor increases from zero to the value of EMF of battery but battery supplies charge at the constant potential difference.

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.
