Electrostatic force is a conservative force, i.e., the work done by the force in moving a test charge from one point to another is independent of the path connecting the two points. |

Since potential is the energy per unit charge, the unit of potential is Joule/Coulomb, which is called a volt . The unit of the electric field which we have so far been using as Newton/Coulomb is more commonly referred as volt/meter. |
