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.
The standard unit of electrical current flow is called the ampere, usually abbreviated to amp or the single letter A. More detail. One amp is equal to a flow of electrical charge over time of one coulomb per second.The standard unit of electrical charge is the coulomb.he ampere (symbol: A) is the SI Base Unit for electric current, and is defined in terms of the force between two, parallel, current-carrying conductors.
