different between electric potential and potential difference?
Answers
Amount of work done to move a unit charge from one end of the conductor to the other end is known as potential difference.
Amount of work done to move a unit positive charge from infinity to a point is known as electric potential.
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
