Ohm's Law
Ohm's Law describes the relationship between current (), voltage (), and resistance (), so that current, which is the flow of electricity, is defined as:
Given the values for any two variables, we solve for the third, so that voltage, electrical potential energy, is defined as:
And resistance, which impedes the flow of electricity, is:
Conductance (), which is the ability for a material to conduct electricity is defined as the inverse of resistance, and can therefore calculated by Ohm's Law as:

History
Ohm's Law is named after Georg Simon Ohm, who first derived the relationships now known as Ohm's Law.
