ohm (Ω) (ōm) the SI unit of electrical resistance, being that of a resistor in which a current of 1 ampere is produced by a potential difference of 1 volt.
ohm (m)
n. Symbol
A unit of electrical resistance equal to that of a conductor in which a current of one ampere is produced by a potential of one volt across its terminals.
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 (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
the SI unit of electrical resistance, being that of a resistor in which a current of 1 ampere is produced by a potential difference of 1 volt. Symbol Ω.
