**Potential Difference Example**

- 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.

The potential difference of a point in an electrical circuit is typically made with **respect to a reference potential**, such as the common ground. Potential difference is commonly known as **voltage** because volts are the standard unit of measure for this quantity. It is also known historically as pressure and tension.

The electrical potential difference is defined as the **amount of work done to carrying a unit charge** from one point to another in an electric field. In other words, the potential difference is defined as the difference in the electric potential of the two charged bodies.

Potential difference is measured in units called **volts**. Volts are symbolized by the letter V and are the work done per unit charge.
