Two coils are connected in series in one gap of the meterbridge and null point is obtained of the middle of the wire by putting `75Omega` in the other gap. Two coils are then connected in parallel and the null point is obtained again at the middle of the wire when the resistance in the other gap is changed by `57Omega`. Find the resistance of each coil.

Two coils are connected in series in one gap of metre bridge and null point is obtained at the middle of wire by putting 50 ohm resistance in other gap. The two coils are then connected in parallel and it is found that resistance in the other gap has to be decreased by 38 Omega to get the null point at same place as before. Find the resistance of each coil

At which point will the null point be obtained on a metrebridge if the ratio of the resistances in the two gaps is 2:3 ?

At what point the null point be obtained in meterbridge experiment when the ratio of resistance in two gaps is 3:7 ?

In an experiment of meter bridge, a null point is obtaining at the center of the bridge wire. When a resistance of 10 ohm is connected in one gap, the value of resistance other gap is

With an unknown resistance X in the left gap and a resistance of 30 Omega in the right gap of meter bridge . The null point is obtained at 40 cm from the left end of the wire . Find i) the unknown resistance and ii)the shift in the position of the null point , when the resistance in each gap is shunted by a resistance of 8 Omega .

With an unknown resistance X in the left gap and a resistance of 30 Omega in the right gap of meter bridge . The null point is obtained at 40 cm from the left end of the wire . Find i) the unknown resistance and ii)the shift in the position of the null point , when the resistances in both the gaps are increased by 15 Omega .

Two unknown resistances are connected in two gaps of a meter-bridge. The null point is obtained at 40 cm from left end. A 30Omega resistance is connected in series with the smaller of the two resistances, the null point shifts by 20 cm to the right end. The value of smaller resistance in Omega is

Two resistances are connected in the two gaps of a meter bridge. The balance point is 20 cm from the zero end. When a resistance 15 Omega is connected in series with the smaller of two resistance, the null point+ shifts to 40 cm . The smaller of the two resistance has the value.

Two resistances X Omega and Y Omega are connected in the left and right gap of a metre bridge. A null point was found on the bridge wire such that the ratio of lengths of two segments of wire is 2:3 . The distance of the null point was measured from the left end of the wire. When the valueof X is increased by 20 Omega , the position of the null point divides the wire into segments of lengths in the ratio 4:1 .Determine X and Y.

In a Wheatstone's meter-bridge experiment, the null point is obtained in middle one third portion of wire.Why is it recommended?
