Voltage is the difference in potential energy between 2 points. It is a measure of how much energy we can get out of one coulomb of charge between these points. The bigger the difference in potential energy, the bigger the voltage. It is also referred to as electrical potential energy difference. This is pretty self-explanatory. I thought this video had a brief explanation of voltage but it inserted the concept nicely in context of other physics related concepts, current and power. The video did not include, however, an important equation for voltage. Voltage is equal to the change in potential energy per Coulomb of charge which is written as V = ∆PE / q. Potential energy is measured in Joules and charge (q) is measured in Coulombs so one unit of voltage (aside from volts) is Joules per Coulomb (J/c).
