# Capacitor Energy Calculator

The following calculator works out either $$E$$, $$C$$, or $$V$$, given the other two parameters, using the capacitor energy equation:

$$E=\frac{1}{2}CV^2$$
where:
$$E$$ = energy
$$C$$ = capacitance
$$V$$ = voltage

 Variable: Value: Units: Calculate What? Variable Diagram: $$E$$ $$C$$ $$V$$
