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