Unit of resistance is – (1) volt² x ampere (2) volt/ampere (3) ampere/volt (4) volt x ampere
by

1 Answer

Answer :

(2) volt/ampere Explanation: An ohm (0) is the SI derived unit of electrical resistance. By definition, a conductor has an electrical resistance of one ohm when a constant potential difference of one volt applied between its ends produces in this conductor a current of one ampere. A volt per ampere (WA) is the SI derived unit, which is equal to ohm by definition 0 = V/A.
