a unit of electrical resistance equal to the resistance between two points on a conductor when a potential difference of one volt between them produces a current of one ampere
"The technician measured exactly five ohms across the resistor to confirm it was within tolerance."
German physicist who formulated Ohm's law (1787-1854)
"The unit of electrical resistance is named after Georg Simon Ohm, the German physicist who formulated Ohm's law."
In the International System of Units, the derived unit of electrical resistance; the electrical resistance of a device across which a potential difference of one volt causes a current of one ampere. Symbol: Ω
"The technician measured the faulty resistor and found its value was only two ohms instead of the required ten thousand."
