What Is Capacitor Energy?
A capacitor stores energy in its electric field through the voltage applied to it. The stored energy depends on the capacitance and on the square of the voltage.
How is it calculated?
How Is It Calculated?
E = ½ × C × V²
- Enter the capacitance (farad) and the voltage (volt).
Unit: joule (J).
Frequently Asked Questions
What happens to the energy when the voltage doubles?
Since the voltage is squared, the energy increases fourfold.
