84. Two tangent galvanometer A and B are identical in construction, except for the number of turns in the coil. They are connected in series and a current is sent through them. The deflection in A is 45° and that in B is 30°. Calculate the ratio of the number of turns in the two galvanometer. 85. 86. na дв (Hint : [Ans. √√3:1] A coil of tangent galvanometer having diameter 16 cm is set up in magnetic meridian. When current of 0.8 A is passed through the coil, the magnetic needle is deflected through 45°. Find the length of the wire in the coil. Also find the reduction factor of tangent galvanometer. (B. = 2 × 10-¹5 Wb/m², μ = 4 × 10-7 Wb/Am) tan 0 A = tan 0 B ) [Ans.: 1.6 m, 0.8 A] A current of 0.2 A passed through a tangent galvanometer produces a deflection of 30°. Find a current which will produce a deflection of 60°. [Ans.: 0.6 A]
