SI electric resistance measure. It is the electric
resistance between two points of a conductor when a constant difference
of potential of 1 Volt, applied between these two points,
produces in this conductor a current of 1 Ampere, this conductor not
being the force of any electromotive force. Ohm = V/A =
m^2*kg*s^(-3)*A^(-2).
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
