how can ohms law be used to define ohm?
Ohm’s Law:
This law states that the ratio of potential difference between the ends of a conductor to the current flowing through the conductor is a constant. This constant is defined as Resistance of the conductor.ie,
V/I=R
Where R is a constant and known as resistance.The unit of resistance is "ohm".1 ohm is the resistance offered by a current of 1 ampere passing through a current carrying conductor when it 's potential difference is 1 volt
