... proportionality constant R is called the “resistance”, measured in Ohms (Ω). R is measured by applying a known voltage across the resistor and measuring the current through it. The reciprocal of resistance (R–1) is called conductance. Ohm’s law is an empirical law, related to irreversible thermodyna ...
