Question

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

Answer 1

Dear Student,

The energy that is drawn from the battery is the same as that stored in the capacitor plus any losses during charging.
The capacitor will stop charging when it reaches the batery voltage level, at which point it reaches its maximum energy.
The remaining energy in the battery can be much higher.
So commenting on the fraction will be a bit difficult as a part of theory concept.
