What is the Ohm Law?

It states the relationship between the voltage or potential difference and the current passing through a material with electrical resistance. This relationship is linear and is stated as V=I*R, Where V is the voltage applied to the material (expressed in Volts), I is the current flowing through it (expressed in Amperes) and R is its resistance expressed in Ohms.
