What is the Ohm's Law?

 Ohm's Law deal with the relationship between voltage and current in an ideal conductor. This relationship states that the potential difference voltage across an ideal conductor is proportional to the current through it. The constant of proportionality is called the "resistance",  I=v/R or V=RI or  R=V/I

This law defines the relationships between current, voltage and resistance.

Ohm's Law describes the relationship between voltage, electrical resistance and electrical current of a linear resistor
