Question

What is Ohm's law describe it

Answer 1

Ohm's law is a law stating that electric current is proportional to voltage and inversely proportional to resistance.

Answer 2

The potential difference, V, across the ends of a given metallic wire in an electric circuit is directly proportional to the current flowing through it, provided its temperature remains the same. This is called Ohm’s law. In other words .

V is proportional to I

V/I = constant

V/I = r
