Question

Bridge balance equations are ________

(a) easy to derive

(b) independent of the components

(c) complex in nature

(d) real in nature

This question was addressed to me in an international level competition.

This interesting question is from Anderson Bridge, Advantages & Disadvantages of Anderson Bridge in division Measurement of Inductance and Capacitance of Electrical Measurements

Answer 1

Right answer is (c) complex in nature

The best I can explain: An Anderson’s bridge is basically used for the measurement of unknown capacitance value in terms of the self-inductance of one of the ratio arms. It consists of real as well as complex terms. It also comprises of star-delta equivalent networks for impedance computations.
