A galvanometer has a resistance of 16 . It shows full scale deflection, when a current of 20 mA is passed through it. The only shunt resistance available is 0.06 2 which is not appropriate to convert a galvanometer into an ammeter. How much resistance should be connected in series with the coil of galvanometer, so that the range of ammeter is 8 A?
