1.	Unknown resistance is obtained by using which of the following relation?(a) Rx = \(\frac{R_1 R_3}{R_2}\)(b) Rx = \(\frac{R_2 R_3}{R_1}\)(c) Rx = \(\frac{R_2 R_1}{R_3}\)(d) Rx = \(\frac{R_2}{R_1}\)I have been asked this question in an international level competition.Question is from Capacitance Comparison Bridge topic in chapter Measurement of Inductance and Capacitance of Electrical Measurements
Answer» CORRECT answer is (B) Rx = \(\frac{R_2 R_3}{R_1}\) The explanation: The value of the unknown RESISTANCE is obtained by using the relation Rx = \(\frac{R_2 R_3}{R_1}\) at BALANCE condition.
