In a Wheatstone's network, the resistance in cycle order are P = 10Omega , Q = 5Omega , S = 4Omega and R = 4Omega then for the bridge to balance.

The measurement of an unknown resistance R is to be carried out using Wheatstone's bridge. Two students perform an experiment in two ways. The first student R_2 = 10 Omega and R_1 = 5 Omega the other student takes R_2 = 1000 Omega and R_1 = 500 Omega . In the standard arm ,both take R_3 = 5 Omega . Both find R = [R_2/R_1] R_3 = 10 Omega within errors
