Energy Stored in Capacitor Calculator — Formule
## Energy in a Capacitor
A charged capacitor stores energy in its electric field.
### Formula
**E = (1/2) * C * V²**
This energy is released when the capacitor discharges. Doubling the voltage quadruples the stored energy.

Exemple Résolu
A 1000 μF capacitor charged to 12 V.
- E = 0.5 * C * V²
- E = 0.5 * 1000e-6 * 12²
- E = 0.5 * 0.001 * 144
- E = 0.072 J = 72 mJ
