What is the balance equation of Kelvin bridge?(a) Rx = \(\frac{R_2 R_3

1.	What is the balance equation of Kelvin bridge?(a) Rx = \(\frac{R_2 R_3}{R_1}\)(b) Rx = \(\frac{R_1 R_2}{R_3}\)(c) Rx = \(\frac{R_1}{R_2}\)(d) Rx = \(\frac{R_1 R_3}{R_2}\)This question was addressed to me in homework.Query is from Kelvin Bridge in division Measurement of Resistance of Electrical Measurements
Answer» Right answer is (d) Rx = \(\FRAC{R_1 R_3}{R_2}\) Best explanation: The balance equation in a KELVIN bridge is GIVEN by the relation Rx = \(\frac{R_1 R_3}{R_2}\) where, R1, R2, R3, and Rx form the ratio arms Rx is the value of the unknown resistance.
