Energy Stored in Capacitor given Charge and Capacitance Calculator

Calculate Energy Stored in Capacitor





Formula

The formula to calculate the energy stored in a capacitor given charge and capacitance is:

\[ U = \frac{Q^2}{2C} \]

Where:

Definition

Energy stored in a capacitor is the energy that is stored in a capacitor, which is a device that stores electric energy in an electric field.

Charge is a fundamental property of matter that causes objects to experience a force when placed in an electrostatic field.

Capacitance is the ability of a system to store electric charge, typically measured in farads, and is a crucial concept in electrostatics.

Example Calculation

Let's assume the following values:

Using the formula:

\[ U = \frac{0.3^2}{2 \cdot 0.011} \approx 4.09090909090909 \, \text{Joules} \]

The energy stored in the capacitor is approximately 4.09090909090909 Joules.
