Abstract

PURPOSE:To perform measurement easily without cutting a part of a closed circuit while the circuit is in operation, by connecting a voltmeter across a resistance to be measured in the closed circuit, and further connecting an ammeter across another resistance in the same closed circuit. CONSTITUTION:For the measurement of the resistance value of a resistance R1n, a voltmeter 1 having sufficiently high internal resistance is connected across the resistance R1n. Further, an ammeter 2 which has sufficiently low internal resistance is connected across a resistance R2n connected in series to the resistance R1n. When measured values of said voltmeter 1 and ammeter 2 are assumed to V volt and I ampere, then R1n=V/I(OMEGA) is obtained. Similarly, values of other resistances are measured respectively.
