What Is the Unit for Voltage?

Answer

The standard unit for voltage is the volt. This unit is named after Alessandro Volta (1745 1827), who invented what is widely considered to be the first chemical battery. The volt is defined in scientific terms as the difference in electric potential across a wire when a current of one ampere gives one watt of power.
