Question

Onms law basically states that if everything else is constant then

Answer 1

Ohm's law states the following :

The voltage across the conductors is directly proportional to the current flowing in the conductor provided that the temperature and the pressure remains constant .

V ∝ I

Now we remove the sign of ∝ with = by providing a constant.

This constant is R or resistance .

V = I R

This is the formula for Ohm's law.

There are conductors that follow this law . They are called Ohmic conductors.

The rest which do not follow are called Non-Ohmic conductors.
