In a meter Bridge experiment the resistance of resistance box is `16 ohm` , which is inserted in right gap The null point is obtained at `25cm` from the left end The least count for meter scale is `1mm`. The percentage error in calculating unknown resistance is approximately

In a meter bridge experiment the ratio of left gap resistance to right gap resistance is 2:3 the balance point from is

In an experiment to determine an unknown resistance, a 100 cm long resistance wire is used. The unknown resistance is kept in the left gap and a known resistance is put into the right gap. The scale to measure length has a least count 1 mm. The null point B is obtained at 40.0 cm from the left gap. We shell determine the percentage error in the computation of unknown resistance.

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) (i) in series and (ii) in parallel.

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 a meter bridge, the null point is found at a distance of 40 cm from A. If a resistance of 12 Omega in connected in parallel with S the null point occurs at 50.0 cm from A Determine the value of R and S
