Figure 6.32 shows a meter bridge in the (which is nothing but a particle wheastone bridge), consisting of two resistors `X` and `Y` together in parellel with a meter long constantan wire of uniform cross section.


with 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 at a distance of `33.7 cm`. The resistor `Y` is shunted by a resistance of `12 Omega`, and the null point is found to shift by a distance of `18.2 cm`. Determine the resistance of `X` and `Y`.

As shown in the figure, a meter bridge consisting of two resistances P and Q together in parallel with a meter-long wire AB of uniform cross-section. C is a movable contact that can slide along the wire AB . The resistors P, Q and resistances of segments AC and CB of the wire constitude the four arms of bridge. the length AB = 100 cm, P = 4 Omega, Q is a coil of wire. With Q immersed in melting ice the null point is found to be at a distance of 40 cm from A . When the coil Q is heated to 100^@C , a 100 Omega resistor has to be connected in parallel with Q in order to keep the bridge balanced at teh same point. Calculate the temperature coefficient of resistance of the coil. .
