What units of measure are used for electricity?

Answer 1

In the so-called "International System of Units", which are based on metric

units, and which form the basis for the electrical units we use, both work and

energy have the same unit, called the "Joule".

Or to make it more simple.

In particular, for electrical power we use the "Watt" (named after the scientist James Watt):

1 Watt = 1 Joule / Second.

Very nice.

Units with which other electrical quantities are described:

-- Electromotive force (Potential difference) . . . volt

-- Electric charge . . . coulomb

-- Electric current . . . ampere

-- Impedance/Resistance/Reactance . . . Ohm

-- Admittance/Conductance/Susceptance . . . Siemen / Mho

-- Capacitance . . . Farad

-- Inductance . . . Henry

-- Frequency . . . Hertz / Cycle

-- Wavelength . . . any unit of length

-- Phase . . . any unit of angle

-- Power Factor . . . percent

-- Power ratio . . . decibel (dB)
