volt
Definition
A volt is a unit of electrical potential difference. It is the amount of energy needed to move one coulomb of charge through a conductor with a resistance of one ohm.
Volts are used to measure the difference in electrical potential between two points. The higher the voltage, the greater the difference in potential.
Volts are used in many different ways, including in batteries, power supplies, and electrical circuits. They are also used to measure the voltage of lightning strikes.
How can the word be used?
The battery has a voltage of 12 volts.
Different forms of the word
