Stored Energy vs Capacitance
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.
Example Calculation
A 1000 μF capacitor charged to 12 V.
- 01E = 0.5 * C * V²
- 02E = 0.5 * 1000e-6 * 12²
- 03E = 0.5 * 0.001 * 144
- 04E = 0.072 J = 72 mJ
