Define the potential difference between two points.

By Ritesh|Updated : November 6th, 2022

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.

Potential Difference Between Two Points

The potential difference between two points in a conservative vector field is referred to as the potential difference. The amount of effort put forward by an external agent to move a unit charge from one position to another is referred to as the potential between two points.

  • The potential difference's mathematical form is

Electrical potential difference = work done (W)/ Charge (Q)

  • The unit of potential difference is Volt (V)

1 volt = 1 joule/ 1 coulomb

Summary:

Define the potential difference between two points.

The amount of effort required to move a unit positive charge from one location to the other without accelerating is known as the potential difference between the two points. The potential difference can be written in Mathematical form as Electrical potential difference = work done (W)/ Charge (Q).
