Enter the capacity (C) and the Voltage (V) of a capacitor to calculate the energy (E) and charge (Q) stored in that capacitor. A capacitor is an electronic instrument used to store an electrical charge.

## Capacitor Energy Formula

The following equation is used to calculate the total store energy in a capacitor.

E = 1/2 * C * VĀ²

- Where E is the energy
- C is the capacitance
- and V is the voltage.

This calculator also determines the charge of the capacitor, which is typically calculated through the following formula:

Q = C*V

- Where Q is the charge
- C is the capacitance
- V is the voltage

Another aspect of calculating the energy stored in a capacitor is the type of capacitor. This could be either parallel plates or spherical capacitors. In each case, however, these plates carry charged particles that are made up of a certain amount of energy. This energy in turn creates an electric field, which is a type of potential energy.

## Capacitor Energy Definition

Capacitor energy is defined as the total energy that can be stored within the electrical component capacitor.

## How to calculate capacitor energy?

How to calculate capacitor energy?

**First, determine the capacitance.**The capacitance is determined by the design and material used in the capacitor.

**Next, determine the voltage.**Determine the voltage moving through the capacitor.

**Finally, calculate the capacitor energy.**Calculate the total energy stored in the capacitor using the formula above.

## FAQ

**What is capacitor energy?**

Capacitor energy is defined as the energy stored in a capacitor due to its capacitance and the voltage running through it.

**What are the units for capacitor energy?**

The units this calculator uses are Farads (F) for capacity, volts (V) for voltage, coulombs (C) for a charge, and Joules (J) for Energy. It’s important that the units entered in the calculate above match these, otherwise, the resulting calculation will be incorrect.
