An ammeter whose resistance is 180 ohms gives full scale deflection when current is 2mA. The shunt required to convert it into an ammeter reading 20mA is :

A moving coil galvanometer of resistance 20 Omega gives a full scale deflection when a current of 1mA is passed through it. It is to be converted into an ammeter reading 20 A on full scale. But the shunt of 0.005 Omega only is available. What resistance should be connected in series with the galvanometer coil?
