Ohm's Law states that in a simple circuit, the Current (I) is directly proportional to the voltage (V) and indirectly proportional the resistance (R) as long as the ambient temperature remains constant.

So that is the written expression of Ohm's Law

This is the mathimatical expression of Ohm's Law

U = I x R
