Electrical Units of Measure. The standard SI units used for the measurement of voltage, current and resistance are the Volt [ V ], Ampere [ A ] and Ohm [ Ï ] respectively.
in electric current. ...current is the ampere, a flow of one coulomb of charge per second, or 6.2 Ã 10 electrons per second. The centimetreâgramâsecond units of current are either the electrostatic unit of charge (esu) per second or the absolute electromagnetic unit (abamp). One abamp equals 10 amps; 1 amp equals 3 Ã 10 esu per second.
