Which unit is used to measure electrical resistance?

Explanation:
Resistance is measured in the ohm. This unit comes from Ohm's law, which relates resistance to voltage and current as R = V / I. An ohm is defined as the resistance between two points of a conductor when a constant potential difference of one volt, applied to those points, would produce a current of one ampere. In other words, amps measure current, volts measure voltage, and watts measure power, while resistance specifically uses the ohm.
