Volt is the electrical unit of voltage. One volt is the energy of 1 joule that is consumed when electric charge of 1 coulomb flows in the circuit. 1V = 1J / 1C. Ampere (A) Ampere is the electrical unit of electrical current. It measures the amount of electrical charge that flows in an electrical circuit per 1 second. 1A = 1C / 1s. Ohm (Ω) Ohm ...
Electricity Unit - Standard Units. The Volt [V], Ampere [A], and Ohm [] are the standard units of electrical measurement for voltage, current, and resistance, respectively. Other commonly used electrical units are derived from SI base units.

Electricity. A unit of electrical energy, particularly for utility bills, is the kilowatt-hour (kWh); [3] one kilowatt-hour is equivalent to 3.6 megajoules. Electricity usage is often given in units of kilowatt-hours per year or other periods. [4]
The standard unit of inductance is the henry abbreviated H. This is a large unit and more commonly used units are the microhenry abbreviated μH (1 μH =10-6H) and the millihenry abbreviated mH (1 mH =10-3 H). Occasionally, the nanohenry abbreviated nH (1 nH = 10-9 H) is used.
Formal definitions of the standard electrical units: ampere, coulomb, charge on an electron, and the volt. Written by Willy McAllister.
