WebVoltage is defined as potential energy per charge: V = E q. There's nothing to prove. But, I think you are really looking for the gain or loss in potential energy formula: Δ V = Δ E / q. you just consider the voltage at point A, and the voltage at point B then subtract them. V A − V B = E A q − E B q, which is the same thing as: Δ V = Δ E / q.

Voltage, Current, Resistance, and Ohm

WebVoltage is often used as a shorthand term for voltage difference, which is another name for potential difference.Voltage measures the energy that a charge will get if it moves between two points in space.
