Abstract
A measurement apparatus comprising a serial resistor in series with an element under measurement; a switching section that sequentially selects ends of a serial circuit including the element under measurement and the serial resistor, and ends of the serial resistor; an applying section that applies an application voltage or application current corresponding to a preset setting value, to each of the sequentially selected ends; a measuring section that, for each of the sequentially selected ends, measures current when the applying section applies the application voltage corresponding to the setting value and measures voltage when the applying section applies the application current corresponding to the setting value; and a resistance calculating section that calculates the resistance value of the element under measurement, based on either the setting values set sequentially in the applying section or measured values measured sequentially by the measuring section for each of the sequentially selected ends.
