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:
\[ Q = C \times V \]
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.
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.
