Learning Objectives

Indicator: 2.3.1.LI.4 - Define and calculate potential difference

By the end of the lesson, learners can:

Define electric potential as the work done per unit charge in bringing a positive test charge from infinity to a point in an electric field.
Define potential difference as the work done per unit charge in moving a charge between two points in an electric field.
State the SI unit of potential difference (volt) and express it in terms of joules per coulomb.
Calculate potential difference using the formula V = W/Q, given values of work done and charge.
Distinguish clearly between electric potential at a point and potential difference between two points.
