What is ohm's law

Answer

Hemanth

A potential difesrnce,V, across the ends of a given metallic wire in an electric circuit is directly propotional to the current flowing through it, provided its temperature remains constant 
       V∝I 
       V/I= constant 
       V/I = R

According to this law the potential difference (voltage) across an ideal conductor is proportional to the current flowing through it.
This law can be given as V = IR
Where ‘R’ is a constant of proportionality called as ‘résistance. Its unit is ohms.
V = potential difference between two points. Its unit is volts.
I = Current flowing through it. Its unit is amperes.
