Two resistances of values `20 Omega and 20 Omega` are introduced in the left and right gaps of a metre bridge. What is the shift in the null point if a resistance of `40 Omega` is connected in series with the resistance in the left gap ?

Two equal resistances are introduced in two gaps of a metre bridge.Find the shift in the null point if an equal resistance is connected in series with resistance in left gap .

Two equal resistances are introduced in two gaps of a metre bridge. The shift in the null point if an equal resistance is connected in series with resistance in left gap is

When an unknown resistance and a resistance of 4Omega are connected in the left and right gaps of a meterbridge, the balance point is obtained at 50 cm. the shift in the balance point if a 4Omega resistance is now connected in parallel to the resistance in the right gap is

When an unknown resistance and a resistance of 4Omega are connected in the left and right gaps of a meterbridge, the balance point is obtained at 50 cm. the shift in the balance point if a 4Omega resistance is now connected in parallel to the resistance in the right gap is

When an unknown resistance and a resistance 6Omega are connected in the left and right gaps of a meter bridge the balance point is obtained at 50 cm. if 3Omega resistance is connected in parallel to resistance in right gap, the balance point is

When unknown resistance and a resistance of 5 Omega are used in left and rigt gaps of meter bridge the balance point is 50 cm. The balancing point of 5Omega resistance is now connected in seriece to the resistor in right gap

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.
