Electric Potential in General Physics 12th Grade: Quarter 3 Week 2

Voltage is directly related to the potential energy in a system. They are not the same thing, but the voltage is a measure of the energy per unit charge.

The energy delivered by a battery can be calculated by multiplying the voltage of the battery by the total charge it delivers.

Voltage is a measure of energy per unit charge, while energy is the total amount of stored energy in a system.
