Q: The difference in electric potential energy which allows for an electric charge to move from one position to another is measured by what si unit?


Read this paragraph and choose the correct option from the provided answers:

In general, for an electric charge to move from one position to another, there must be a difference in electric potential energy between the two positions. The difference in electric potential energy is called potential difference, or voltage . Voltage is measured in an SI unit called the volt (V). For example, the terminals of the car battery in Figure below have a potential difference of 12 volts. This difference in voltage results in a spontaneous flow of charges, or electric current.

 Choices:

- ohm

- joule

- meter

- volt


A:
volt
