Question

A galvanometer having a resistance of 50N gives a full scale deflection
for a current of 0.05A. The length in metre of a resistance wire of area of
cross section 2.97 x 10-2 cm 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 x 10-79 - m)​
