Switch S, applies battery voltage to the four resistors in the bridge. To balance the bridge the value of R, is varied. Balance is indicated by zero current in galvanometer G when switch S is closed. Q9. Rz. an unkniown resistor R/R2, ratio arm Ri, standard resistor V S. Then the value of R, is (c) R,R (d) R, +R M R R (a) ,R R. = R, (b) R, = R O O(b) O O d)
