WebThat's the beauty of using a Wheatstone's bridge Because we know the ratio of lengths of the two wires ( and with it the ratio of their resistances, R/R'= L/L' ) we also know the resistance of one of the other resistors, we can, with some maths ( R : Known resistance :: Rwire : Rwire' ) find out the resistance of the object (a banana in this case) WebIn a Wheatstone’s bridge P = 100 Ω, Q = 1000 Ω and R = 40 Ω. If the galvanometer shows zero deflection, determine the value of S. Solution EXAMPLE 2.24 What is the value of x when the Wheatstone’s network is balanced? P = 500 Ω, Q = 800 Ω, R = x + 400, S = 1000 Ω Solution P/Q = R/S x + 400 = 0.625 × 1000 x + 400 = 625 x = 625 – 400 x = 225 Ω
