Calculate Capacitor Energy



Formula

The formula to calculate the energy stored in a capacitor (E) is:

\[ E = \frac{1}{2} C V^2 \]

Where:

The formula to calculate the charge (Q) is:

\[ Q = C \times V \]

What is Capacitor Energy?

Capacitor energy is defined as the total energy that can be stored within the electrical component capacitor. This energy creates an electric field, which is a type of potential energy.

Example Calculation

Consider an example where:

Using the formula to calculate the energy stored in the capacitor:

\[ E = \frac{1}{2} \times 0.01 \times 12^2 = 0.72 \text{ Joules} \]

Using the formula to calculate the charge:

\[ Q = 0.01 \times 12 = 0.12 \text{ Coulombs} \]

This means that the energy stored in the capacitor is 0.72 Joules and the charge is 0.12 Coulombs.
