## ohm

(Ω) [ōm]
the SI unit of electrical resistance, named for Georg Simon Ohm; one ohm is produced when a current of 1 ampere flowing through a conductor produces a potential difference of 1 volt. Impedance is also measured in ohms.

## ohm (Ω),

(ōm),
The practical unit of electrical resistance; the resistance of any conductor allowing 1 A of current to pass under the electromotive force of 1 V.

## ohm (Ω)

Etymology: Georg S. Ohm, German physicist, 1787-1854
a unit of measurement of electric resistance. One ohm is the resistance of a conductor in which an electrical potential of 1 volt produces a current of 1 ampere. See also ampere, Ohm's law, volt, watt.

ohm - the practical unit of electrical resistance.
Ohm law - in an electric current passing through a wire, the intensity of the current in amperes equals the electromotive force in volts divided by the resistance in ohms.
