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?
