Q.

A galvanometer having a resistance of 50Ω , gives a full scale deflection for a current of 0.05 A. The length in meter of a resistance wire of area of cross section 2.97 x 10–2 cm2 that can be used to convert the galvanometer into an ammeter which can read a maximum of 5A current is ( specific resistance of the wire = 5×10-7Ω-m
