What is the dependence of frequency on the balance equation?(a) independent(b) varies by a factor of 2(c) depends on the supply magnitude(d) depends on the detector usedThe question was asked in a national level competition.This interesting question is from High Voltage Schering Bridge in portion Measurement of Inductance and Capacitance of Electrical Measurements

Answer»

Right CHOICE is (a) independent

Explanation: In a high voltage Schering bridge, the balance equation does not depend on the FREQUENCY of OPERATION of the circuit. A DETECTOR is only used for detecting the balance CONDITION in a bridge circuit.
