Enter the electrical charge and total work done into the calculator to determine the potential difference.

## Potential Difference Formula

The following formula is used to calculate the potential difference between to points.

PD = W / C

- Where PD is the potential difference (V)
- W is the work done (J)
- C is the charge (C)

## Potential Difference Definition

A potential difference is defined as the ratio of the work performed to the charge of an electrical system, or in other words the electric potential energy.

## Potential Difference Example

How to calculate potential difference?

**First, determine the work done.**Calculate the total amount of work done on the electrical system or circuit.

**Next, determine the charge.**Measure the charge between the two locations in the system.

**Finally, calculate the potential difference.**Calculate the potential difference using the formula above and the work and charge from steps 1 and 2.

## FAQ

**What is a potential difference?**

A potential difference is also often referred to as the electric potential. It’s a measure of the electric potential energy contained within a closed circuit or system.

**What causes potential difference?**

An electrical potential is created through the flow of electrical charge across a circuit.
