What is voltage?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Voltage is the electrical potential difference between two points in a circuit. It represents the "pressure" or "force" that pushes electric charges through a conductor. Measured in volts (V), voltage is what causes current to flow when a circuit is complete. Think of it like water pressure in pipes—higher voltage means greater potential to move charges, just as higher water pressure can move more water. Common household voltage is 120V in the US and 230-240V in many other countries.
