difference between electric potential and potential difference
Answers
Answer:
Electric potential is the work done to bring the electron to the unit test charge whereas potential difference is the work done to move the electron from one point to another in the unit test charge itself.

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
