A coil of unknown resistance is placed in the left gap of a metre bridge and a resistance R is placed in the right gap. The null point is obtained at a distance of 40 cm from the left end. When a resistance of 10 ohm is connected in series with the coil and the same resistance R is kept in the right gap,the null point is obtained at the centre of wire. Find the resistance of the coil.

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.

Accuracy of a metrebridge is maximum when the null point is obtained at the midpoint of the bridge wire. This is because

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

A uniform wire is cut into two pieces such that on piece is twice as long as the other. The two piece are connected in parallel in the left gap of a meterbridge. When a resistance of 20Omega is connected in the right gap, the null point is obtained at a distance of 60cm from the right end of the wire. Find the resistance of the wire before it was cut into two pieces.

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 unknown resistrance X and Y are connected to left and right gaps of a meter bridge and the balancing point is obtained at 80 cm from left. When a 10Ω resistance is connected in parallel to x, the balance point is 50 cm from left. The values of X and Y respectively are

In a meter bridge experiment, the unknown resistance X in the left gap and a known resistance of 60 Omega in right gap, null point is obtained at l cm from left. If the unknown resistance X is shunted by an equal resistance, what should be the value of known resistance in the right gap in order to get the null point at the same place?

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
