2. The circuit shown below is Wheatstone bridge used to determine the value of an unknown resistor X by comparison with three resistors M, N, and P whose resistances can be varied.
For each setting, the resistance of each resistor is precisely known. With switches K1 and K2
closed, these resistors are varied until the current in the galvanometer G is zero; the bridge is
then said to be balanced. (a) If the galvanometer G shows zero deflection when M = 850.0 Ω,
N = 15.00 Ω, and P = 33.48 Ω, what is the unknown resistance X?
