The formula to calculate the energy stored in a capacitor is:
\[ U_e = \frac{1}{2} Q V \]
Where:
Electrostatic potential energy is the energy associated with the interaction between two or more point charges at rest in a particular position.
Charge is a fundamental property of matter that causes objects to experience a force when placed in an electrostatic field.
Voltage is the electric potential difference between two points, measured in volts, and is a fundamental concept in understanding electrostatic forces and interactions.
Let's assume the following values:
Using the formula:
\[ U_e = \frac{1}{2} \cdot 0.3 \cdot 120 = 18 \text{ J} \]
The energy stored is 18 Joules.
