Work done by battery to charge a capacitor #!#Energy density

How many percent of work done by a battery is consumed to fully charge a capacitor which is stored as electric potential energy in the capacitor ?

A capacitor is getting charged by a battery of emf V what is the ratio of heat dissipated in the resistor to work done by battery when charge on capacitor is CV/2

A parallel plate capcitor of capacitance C is charged to a potential V by a battery. Without disconencting the battery = distance between the plates of capacitor is triple and a dielectric medium of K = 10 is introduced between the plates of capacitor. Explain giving reasons how will the following be affected ? (a) Capacitance of capacitor (b) Charge on capacitor (c ) Energy density of capacitor.

In a charged capacitor, the energy resides in

A parallel plate capacitor is charged by a battery after charging the capacitor, battery is disconnected and decrease the distance between the plates then which following statement is correct ?

In a charged capacitor, the energy is stored in

The plates of a parallel plate capacitor are charged with a battery so that the plates of the capacitor have acquired the P.D. equal to e.m.f of the battery. The ratio of the work done by the battery and the energy stored in capacitor is

An initially uncharged capacitor C is being charged by a battery of emf E through a resistance R upto the instant when the capacitor is charged to the potential E/2, the ratio of the work done by the battery to the heat dissipated by the resistor is given by :-
