An unknown resistance is connected in a left gap of a metre bridge . The balance point is obtained when a resistance of `10 Omega` is taken out from the resistance box in the right gap. On increasing the resistance from the resistance box by `12.5 Omega` the balance point shifts by 20 cm.
find the unknown resistance.

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

A resistance of 2Omega is connected across one gap of a metre-bridge(the length of the wire is 100 cm) and an unknown resistance, greater than 2Omega , is connected across the other gap. When these resistances are interchanged, the balance points shifts by 20 cm. Neglecting any corrections, the unknown resistance is

A resistance of 2Omega is connected across one gap of a meter bridge (the length of the wire is 100 cm ) and an unknown resistance, greater than 2Omega is conneted across the other gap. When these resistances are interchanged, the balance point shifts by 20 cm . Neglecting any corrections,the unknown resistance is

If the balance point is obtained at the 35th cm in a metre bridge the resistances in the left and right gaps are in the ratio of

A resistance of 2 Omega is connected across one gap of a meter bridge (the length of the wire is 100 cm and an unknown resistance, greater than 2 Omega , is connected across the other gap. When these resistance are interchanged, the balance point shifts by 20cm . Neglecting any corrections, the unknown resistance is. (a) 3 Omega (b) 4 Omega ( c) 5 Omega (d) 6 Omega .

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

Two resistances are connected in two gaps of a metre bridge. The balance point is 20cm from the zero end. A resistance of 15Omega is connected in series with the smaller of the two. The null point shifts to 40cm. Then value of the smaller resistance Is:

Two equal resistance are connected in the gaps of a metre bridge. If the resistance in the left gap is increased by 10% the balancing point shift
