Abstract. Possibilities of method of three voltmeters are investigational for measuring of inductance of pure resistance, and also their frequency descriptions. It is set that in the range of frequencies to 100 kHz the error of measuring of inductance makes no more than 0,3%, pure resistance - 8,65%.

Keywords: inductance, resistance, impedance, method of three voltmeters, measuring, frequency description, good quality, error, exemplary measure.
