Question

What is ohm law ?explain how it used to define the unit of resistance

Answer 1

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

Answer 2

Answer:

Ohm's Law：

It state that electric current flowing through a metallic wire is directly ptoportional difference across. it ends provided its temperature remains same.

V/I= constant=R

V=IR

It is the constant and called resistance
