A moving coild 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 20A. But the resistance of the only shunt available is `0.005Omega`. What resistance should be connected in series with the galvanometer coil?
