Ohm is the SI unit of electrical.
A
Conductivity
B
Resistance
C
Hardness
D
Flow
Explanation: 

Detailed explanation-1: -The SI unit of electric resistance is the ohm (). 1 = 1 V/A.

Detailed explanation-2: -The SI unit of resistance is ohm (symbol ). One ohm is said to be that resistance of a conductor, which is offered when a current of one ampere flows in it while a potential difference of one volt is applied to it.

Detailed explanation-3: -Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Therefore, V = RI where R is a constant called resistance. R depends on the dimensions of the conductor and also on the material of the conductor. Its SI unit is Ohm ().

Detailed explanation-4: -One-ohm is equal to 1 volt / 1 ampere. The SI unit of electrical resistance i.e Ohm is named in honour of the 19th-century German physicist Georg Simon Ohm.
