  • Patent number: 8473232
    Abstract: A measuring apparatus is capable of separately measuring at least one of the purely resistive component and the reactance component of a measured circuit. The measuring apparatus applies an AC voltage to the measured circuit and detects a current flowing in the measured circuit. When doing so, a first detection signal whose amplitude changes in accordance with an amplitude of a real component of the current and a second detection signal whose amplitude changes in accordance with an amplitude of an imaginary component are generated. The at least one of a purely resistive component and a reactance component of the measured circuit is then calculated using the first detection signal and the second detection signal.
