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