Detailed Solution

The unit of electrical resistance is the ohm.
The property of opposing the flow of current through a conductor by itself is called resistance. The ratio of potential difference across the conductor’s ends to the current flowing through it is equal to the resistance of the conductor.
Constant R= Potential differencecurrent
Or  R= VI
The resistance of a conductor is affected by the length, thickness, nature of material and temperature of the conductor.
