AP and TS EAMCET Engineering Model Paper 16

In meter bridge experiment, four wires of same material are connected m the left gap one after other whose lengths and radii are given below. A standard resistance is connected in the right gap. Arrange the balancing lengths in ascending order
(a) l = 50 cm, r = 0.5 mm
(b) l = 100 cm, r = 1 mm
(c) l = 200 cm, r = 2 mm
(d) l = 300 cm, r = 3 mm
