The electric voltage indicates how strong the drive of the electric current is.
Formula symbol: U
Unit: one volt (1 V)
Multiples of the unit 1 V are one kilovolt (1 kV) and one megavolt (1 MV): 1 MV = 1,000 kV = 1,000,000 V
Part of the unit 1 V is one millivolt (mV): 1 V = 1,000 mV
Electrical voltage is measured with voltmeters, also called voltmeters.
The unit of electrical voltage is named after the Italian naturalist ALESSANDRO VOLTA (1745 - 1827).
