Show that the percentage error in the measurement of resistance by a metre bridge is minimum when the null point is near about the centre of the wire.

The accurate measurement of emf can be obtained using.

The circuit diagram given in the figure shown the experimental setup for the measurement of unknown resistance by using a metre bridge. The wire connected between the points P and Q(PQ = 100 cm) has uniform cross-sectional area and its resistivity is directly proportional to the distance from point P. Null point is obtained with the jockey J with R_1 and R_2 in the gaps. If R_1 and R_2 are interchanged, the jockey has to be displaced through a distance from the previous position along the wire to establish the null point. If the ratio of R_1/R_2=3 , the value of Delta (in cm) is: [Ignore any end corrections]

With an unknown resistance X in the left gap and a resistance R in the right gap of a meter bridge, the neutral point is obtained at a distance of 75cm from the left end. The shift of null point if the unknown resistance is shunted by an equal resistance X and keeping same resistance in right gap is

An unknown resistance 'X' is placed in the left gap and and a known resistance of 60Omega is plaecd in the right gap of metre bridge. The null point is obtained at 40 cm from the left end fo the bridge. Fid the unknown resistance.

Two coils are connected in series in one gap of the Wheatstone's meter bridge and null point is obtained at the centre of the wire with a resistance of 100 Omega in the other gap. When the two coils are connected in parallel in the same gap, the unknown resistance is to be changed by 84 Omega to obtain the null point at the centre again. The resistance of the two coils will be
