The resistance in the left gap of a metre bridge is `10Omega` and the balance point is 40 cm from the left end. Calculate the value of unknown resistance.

The resistance in the left gap of a metre bridge is 10Omega and the balance point is 40 cm form the left end. Calculate the value of the unknown resistance.

Two parallel resistors of 5 ohm nd 20 ohm are connected in left arm of a metre bridge. If the null point is at 40 cm from left end of the wire, calculate the value of resistance connected in right arm.

In a metre bridge, the balancing length form the left end is focused to be 20 cm. The value of the unknown reistance is

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.

In a meter bridge when the resistance in the left gap is 2 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 2 Omega , find the shift of the balance point on the bridge wire

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

With two resistance R_1 and R_2 (>R_1) in the two gaps of a metre bridge the balance was found to be 1/3 m from the zero end. When a 6 Omega resistance is connected in series with the smaller of the two resistance, the point is shifted to 2/3 m from the same end, then R_1 and R_2 Find the resistance of the two wires.

In a meter-bridge experiment with a resistance R_(1) in left gap and a resistance X in a right gap. null point is obtained at 40 cm from the left emf. With a resistance R_(2) in the left gap, the null point is obtainned at 50 cm from left hand. Find the position of the left gap is containing R_(1) and R_(2) in series.
