How is the bridge balanced?(a) using resistance R1(b) using resistance

1.	How is the bridge balanced?(a) using resistance R1(b) using resistance R3(c) through capacitance C3(d) through capacitance CxI had been asked this question in a national level competition.Asked question is from Capacitance Comparison Bridge in division Measurement of Inductance and Capacitance of Electrical Measurements
Answer» Correct choice is (b) using resistance R3 For explanation I WOULD say: Bridge balance is obtained by varying the resistance R3. At balance we get the value of the UNKNOWN resistance as Rx = ^R1 R3⁄R2.
