Unknown capacitance is found by using which of the following relation?

1.	Unknown capacitance is found by using which of the following relation?(a) Cx = \(\frac{C_3 R_2}{R_1}\)(b) Cx = \(\frac{C_3}{R_2}\)(c) Cx = \(\frac{C_3 R_1}{R_2}\)(d) Cx = \(\frac{R_1}{R_2}\)I had been asked this question by my college professor while I was bunking the class.The origin of the question is Capacitance Comparison Bridge in division Measurement of Inductance and Capacitance of Electrical Measurements
Answer» The CORRECT choice is (c) Cx = \(\frac{C_3 R_1}{R_2}\) Easiest explanation: The VALUE of unknown capacitance is FOUND using the relation Cx = \(\frac{C_3 R_1}{R_2}\)at BALANCE CONDITION.
