1.	At very low frequencies in a AC bridge, the source is _________(a) power line(b) e.m.f(c) galvanometer(d) tuned circuitI had been asked this question in a job interview.I'm obligated to ask this question of Sources and Detectors in chapter Measurement of Inductance and Capacitance of Electrical Measurements
Answer» Correct answer is (a) power LINE To explain: GALVANOMETER is used for detecting the balance condition. The power line acts as a source of supply for bridge MEASUREMENTS in an AC bridge CIRCUIT at very low frequencies.
