Explanation: The ohm (Ω) is the unit of measurement for resistivity in the SI system. It is defined as the resistance between two points of a conductor when a constant potential difference of one volt, applied to these points, produces in the conductor a current of one ampere, the conductor not being the source of any electromotive force.
