The resistances in left and right gap of a meter brigdge are 20 `omega` and 30 `omega` respecitively when the resistance in the left gap is reduced to half its value then balance point shifts by

The resistance in two gaps of a meter bridge are 10 Omega and 30 Omega respectively. If the resistances are interchanged the balance point shifts by

Resistance in the two gaps of a meter bridge are 10Omega and 30 Omega respectively . If the resistances are interchanged the balance point shifts by

The resistances in the left and right gaps of a metre bridge are 10 Omega and 30 Omega respectively. If the bridge is balanced, then the distance of the null point from the centre of the wire is

Resistance in the two gaps of a meter bridge are 10 ohm and 30 ohm respectively. If the resistances are interchanged he balance point shifts by

A certain unknown resistance is connected in the left gap and a resistance box in the right gap of a metre bridge. By introducing a resistance of 10 Omega with the help of resistance box, the balance point is determined. If the balance point shift by 20 cm on increasing the resistance from the resistance box by 12.5 Omega Find the value of unknown resistance.

With a resistance P Omega in the left gap and another resistance Q Omega in the right gap of a meter bridge, the balance point is obtained at 40 cm. When a resistance of 6 Omega is connected across Q, the balance point shifts to 50 cm. The value of resistance P 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

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

In a meter-bridge if the left and right gaps are connected with 2 Omega and 3 Omega resistances, respectively then the bridge is balanced. The resistance to be connected with 3 Omega resistance to get the balancing point at midpoint of the bridge wire is

A metre bridge is balanced with known resistance in the right gap and a metal wire in the left gap. If the metal wire is heated the balance point.
