# Electric Potential and Potential Energy

**ELECTRIC POTENTIAL AND POTENTIAL DIFFERENCE**

The electric potential at a point is defined as work done in bringing a unit positive charge from infinity to that point. The potential difference between two points is defined as the difference in electric potentials at the two given points. The electrons move only if there is a difference in electric pressure called the potential difference. One Volt is defined as energy consumption of one joule per electric charge of one coulomb.

Mathematically, electric potential between two points is given as:

V=W/Q

Where V is the potential difference, W is the work done, Q is the electric charge.

One volt is the potential difference between two points in a current carrying conductor when 1 joule of work is done to move a charge of 1 coulomb from one point to the other.
