Voltage is defined as the difference of potential.

Explanation:
Voltage is the potential difference between two points in an electric field. It represents how much energy per unit charge is available to move charges from one point to another, and that difference “pushes” current through a circuit. In other words, voltage is the difference of potential. It isn’t energy by itself (energy relates to charge carrying E = VQ, but voltage is the per-charge potential difference), nor is it the current (the flow of charge), nor the resistance (the property that resists that flow). The key idea is that the voltage measures how different the electric potential is between two points, which drives the movement of charge.
