Explanation:
An electric potential (also called the electric field potential, potential drop or the electrostatic potential) is the amount of work needed to move a unit of charge from a reference point to a specific point inside the field without producing an acceleration. Typically, the reference point is the Earth or a point at infinity, although any point can be used.
The SI "Unit of potential difference" is Volt. It is "the difference of potential" that would carry "one ampere of current" against one ohm resistance. Explanation: ... The S.I unit of potential difference is volt. One volt is equal to the energy consumed by one joule per electric charge.

Answer:
hey mate
Explanation:
here is your answer:
Definition: The electric potential difference between two points in an electric field is defined as the work done per unit charge by an external agent against the electric force in moving an infinitesimal positive charge from one point to the other without acceleration.
The SI unit of electric potential difference is the volt named after Italian physicist Alessandro Giuseppe Anastasio Volta (1745—1827)
Definition:The electric potential difference between two points in an electric field is on volt if the work done per unit charge by an external agent against the electric force in moving an infinitesimal positive charge without acceleration from one point to the other is one joule per coulomb.
