Stored Energy vs Capacitance
Formel
## 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.
Lösungsbeispiel
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
Häufig Gestellte Fragen
Why does energy scale with voltage squared?
As voltage increases, both the stored charge and the voltage across the capacitor increase, giving a quadratic relationship.
Can a capacitor replace a battery?
Supercapacitors can store significant energy for short bursts, but batteries store far more energy per unit mass for sustained delivery.
Is it dangerous to discharge a charged capacitor?
Large capacitors at high voltages can store lethal amounts of energy. Always discharge capacitors safely before handling.
