The current through a conductor between two points is directly proportional to the voltage across the two points.

Explanation:

When you have a current running through a conductor between two points, its value can be calculated if one knows the voltage and the resistance, since the current is proportional to the coltage, and the resistance is the constant of proportionality. This law can be simplified into one nifty equation:

#I=V/R#, where #I# is the current through the conductor in 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. Additionally, Ohm's law states that #R# is constant and independent of the current.

For example, if we have a circuit which has a resistance (#R#) of 2, and voltage (#V#) of 2, we can plug these values into the equation to find the current, which is
#I=2/2#
#I=1# amp

This is what Ohm's Law states.
