In a meter bridge, the gaps are closed by resistances 2 and 3 ohms. The value of shunt to be added to 3 ohm resistor to shift the balancing point by 22.5 cm is

In a metre bridge, the gaps are closed by two resistance P and Q and the balance point is obtained at 40 cm . When Q is shunted by a resistance of 10 Omega , the balance point shifts to 50 cm . The values of P and Q are. .

In a meter bridge experiment two unknown resistance X and y are connected to left and right gaps of a meter bridge and the balancing point is obtained at 20 cm from right (XgtY) the new position of the null point from left if one decides balance a resistance of 4 X against Y.

In a meter bridge when the resistance in the left gap is 4 Omega and an unknown resistance in the right gap the balance point is obtained at 40 cm from the zero end. On shunting the unknown resistance with 4 Omega , find the shift of the balance point on the bridge wire

In a metre bridge when the resistance in the left gap is 2Omega and an unknown resistance in the right gap, the balance point is obtained at 40 cm from the zero end. On shunting the unknown resistance with 2Omega find the shift of the balance point on the bridge wire.

In the circuit shown, a meter bridge is in its balanced state. The meter bridge wire has a resistance .1 ohm//cm . The value of unknown resistance X and the current drawn from the battery of negligible resistance is

Using three wires of resistances 1 ohm, 2ohm and 3 ohm then no. of different values of resistances that possible are
