A galvanometer of resistance `50 Omega`, gives a full scale deflection for current of 50 mA. It is to be converted intyo an ammeter to read a maximum current 5 A. What should be the length of the resistance wire of specific resisrance` 5xx 10^(-7) Omega` and cross sectional area` 2.97 xx 10^(-2)cm^(2)`, reqiured for this conversion?
