What does voltage refer to in electricity?

Voltage refers to the potential difference that drives electric current in a circuit. It is essentially the force that pushes electric charges to move through a conductor, enabling the flow of electricity. Measured in volts, voltage quantifies the energy per unit charge available to motivate electrons through resistance, which ultimately results in the operation of electrical devices.

This concept is fundamental in understanding electrical systems because without a potential difference, there would be no movement of current, which is necessary for delivering power. Voltage essentially acts as the impetus that allows current to flow, distinguishing it from other electrical parameters like current and resistance, which have different roles in an electrical circuit.

Understanding voltage is crucial for linemen, who must be able to diagnose issues within electrical systems, ensure safe operating conditions, and maintain the integrity of power distribution networks.
