Question

What is the Ohm's law

Answer 1

Ohm's Law deals 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 "R".

Answer 2

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