Question

define one ohms resistance?

Answer 1

The ohm is defined as an electrical 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 seat of any electromotive force.

Answer 2

One ohm is the resistance when potential difference is one colt and current is one ampere
One ohm=one volt/one ampere
