define potential difference

Electric current is the flow of charged particles in a conductor. The electrons move only if there is a difference called the potential difference along the conductor. The difference of potential can be produced by a battery consisting of one or more cell.

We define electric potential difference between two points in an electric circuit carrying some current, as the work done to move a unit charge from one point to the other-

V=W/Q

Where V = potential difference between two points

W =Work done

Q=charge

SI unit is volt (V).

 Electric potential of a point in an electric field is defined as the work to be done to move a unit positive charge from infinity to that point.

Potential difference is the difference in the potential between the two terminals of the battery or any other current source connected in the circuit. For example if we say that we have a battery of 3volts then we mean to say that when this battery will be connect in the circuit then it will maintain a potential difference of 3volts across its terminals

The amount of energy per unit charge needed to move a charged particle from a reference point to a designated point in a static electric field; voltage.
