<P> Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points . Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship: </P> <Dl> <Dd> I = V R, (\ displaystyle I = (\ frac (V) (R)),) </Dd> </Dl> <Dd> I = V R, (\ displaystyle I = (\ frac (V) (R)),) </Dd> <P> where I is the current through the conductor in units of amperes, V is the voltage measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms . More specifically, Ohm's law states that the R in this relation is constant, independent of the current . </P>
