A Method for Determining the Residual Inductance of a Variable Air Capacitor at Radio Frequency

A procedure is outlined which furnishes a method for the measurement of the residual inductances of a standard capacitor and a specimen capacitor which are connected parallel to each other for a substitution measurement. From two junction points connected to a reactance meter, i.e., the high-potential and the earth-potential junction points, the residual inductances of both capacitors, including those of each lead wire, are measured to several percentages at 50 MHz without disconnecting any leads or capacitors or the reactance meter.
