In a charged capacitor, where is the energy stored?

1. In the positive charge distribution
2. Equally in the positive and negative charge distributions
3. In the electric field between the plates
4. Around the edges of the capacitor plates

Correct answer: In the electric field between the plates

Solution

The energy stored in a capacitor resides in the electric field established between its plates. It is not stored in the charges themselves, but in the field configuration created by them.
