Question

what is the difference between potential difference and electric potential

Answer 1

Electric potential energy is a type of potential energy that results from coulomb forces. It is measured in joules and depends on the positioning of charged particles relative to one another, as well as the magnitude of their respective charges.
PD is the voltage of the circuit

Answer 2

What is Electric Potential?

Electric potential (V) is the property of points in space. Electric potential can be defined in several ways:

The value of the electric potential at a point in space numerically gives the amount of work that needs to be done to bring a unit positive charge from infinity to that point.

A charge q is said to have a potential energy of Vq if it is at a point in space which has a potential of V.

For example, if you place a charge q at a point, space nearby will have a non-zero value of potential. The electric potential at a point due to a charge at a distance r from it is given by:

V=kqr

What is Electric Potential Energy?

Electric potential energy (U) is the property of a system. Two charges in the vicinity of each other are said to have potential energy.

The electric potential energy associated with two charges separated by a distance r is given by:

U=kq1q2r
