Question

The amount of work done (energy spent) in moving a unit positive charge from infinity to a given point in an electric field is called:

Options

• potential difference

• electric potential

• terminal voltage

• none of these

Answer 1

Electric potential

Explanation:

Electric potential at a point is the work done in moving a unit positive charge from infinity to that point. Potential difference is the work done between two points, and terminal voltage appears when current is drawn.
