Which the help of a movable contact D, one can change the ratio of resistance of the two segments of the wire until a sensitive galvanometer G connected across B and D shows no deflection. The null point is found to be a distance of 33.7 cm. The resistor Y is shunted by a resistance of 12 ω, and the null point is found to shift by a distance of 18.2 cm. Determine the approximate resistance of X and Y in ohm.

consisting of two resistors X and Y together in parallel with a meter long constantan wire of uniform cross section. Which the help of a movable contact D Figure shows a meter bridge (which is nothing but a practical Wheatstone bridge) if one decides to balance a resistance of 4 X against Y In a meter bridge experiment null point is obtained at 20 cm. from one end of the wire when resistance X is balanced against another resistance Y. If XltY then where will be the new position of the null point from the same end
