Abstract
The resistance of an inductive load is measured by connecting an inductor to the load and applying a pulse of energy to the load and the inductor. The voltage across the inductor is monitored and the load voltage and current are measured when the inductor voltage passes through zero. The ratio of the voltage and current at the instant of zero crossing is equal to the load resistance value. An apparatus for performing this method is disclosed.
