Question
An uncharged capacitor is connected to a battery. On charging the capacitor
- All the energy supplied is stored in the capacitor
- Half the energy supplied is stored in the capacitor
- The energy stored depends upon the capacity of the capacitor only
- The energy stored depends upon the time for which the capacitor is charged
The correct answer is: Half the energy supplied is stored in the capacitor
