A galvanometer has a resistance of $16 \Omega$ and gives a full scale deflection when a current of $20\ mA$ is passed through it. The only shunt resistance available is $0.04 \Omega$ which is not sufficient to convert the galvanometer to an ammeter to measure up to $10 A$. What resistance should be connected in series with the coil of the galvanometer so that the range of the ammeter is $10 A ?$
