1.	The value of unknown inductance is found by using which of the following relation?(a) Lx = \(\frac{R_1 L_3}{R_2}\)(b) Lx = \(\frac{R_2}{R_1}\)(c) Lx = \(\frac{L_3}{R_1}\)(d) Lx = \(\frac{R_2 L_3}{R_1}\)I had been asked this question in a job interview.Question is from Inductance Comparison Bridge in division Measurement of Inductance and Capacitance of Electrical Measurements
Answer» The correct choice is (d) Lx = \(\frac{R_2 L_3}{R_1}\) Easy explanation: At balance condition in an INDUCTANCE comparison BRIDGE, the VALUE of unknown inductance is found by USING the relation Lx = \(\frac{R_2 L_3}{R_1}\).
