Constants Part A The Circuit Shown In Figure 1 Called A Wheatstone Bridge Is Used To Determine The Value Of An Unkno 1 (62.36 KiB) Viewed 19 times

Constants Part A The circuit shown in (Figure 1), called a Wheatstone bridge, is 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 S, and S2 closed, these resistors are varied until the current in the galvanometer Gis is zero; the bridge is then said to be balanced. Under this condition the unknown resistance is given by X = MP/N. If the galvanometer G shows zero deflection when M = 840.0 2, N = 15.00 12, and P = 33.38 2. what is the unknown resistance X?
