Impedance measurement

Japanese: インピーダンス測定 - いんぴーだんすそくてい
Impedance measurement

...The three-phase power measurement is performed using the three-voltmeter method and the three-current method, while the two-wattmeter method, which applies Blondel's theorem, is used to measure three-phase power.
[Impedance measurement]
For simple resistance measurements, testers and ohmmeters are used, and there is also a method of calculating resistance as the voltage/current ratio using a voltmeter and ammeter. For precise measurement, a Wheatstone bridge, Kelvin double bridge, or current comparison bridge is used to compare two resistances using a potentiometer. …
