What is the Ohm Law?

Ohm discovered that the amount of current was directly proportional to the voltage (more voltage gives more current) and inversely proportional to the resistance (more resistance gives less current).

Current = Voltage / Resistance

I = V/R (or V = IR, R = V/I)

This relationship is called Ohm's Law. It also gives us a relationship between the units amperes, volts and ohms:

1 ampere = 1 (volt/ohm)
