Define the potential difference between two points.

The potential difference between the two points is the amount of work done to move a unit of positive charge without accelerating from one point to the other. The difference that might exist between any two points The amount of work required to move a unit positive charge along any path from one point to another without accelerating is referred to as the electric field.

• It is denoted by dV

dV = dw/dq

Alternatively, the potential difference between points A and B is calculated by dividing the charge that has moved from A to B by the shift in a charge's potential energy, or q.

VB - VA = (UB - UA)/ q = WAB/q = dV

• Volt is the electrostatic potential difference's corresponding SI unit.
• If one joule of labor is required to move a charge of one coulomb from one place to another in an electric field, the potential difference is said to be one volt.
• Energy is released when a positive charge is transported from a place with a greater potential to a point with a lower potential.
