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 two 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?

  1. First, determine the work done.

    Calculate the total amount of work done on the electrical system or circuit.

  2. Next, determine the charge.

    Measure the charge between the two locations in the system.

  3. 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?
