The current flowing in a coil of resistance `90 Omega` is to be reduced by 90%. What value of resistance should be connected in parallel with it

The current flowing through a coil of resistance 900 Omega is to be reduced by 90% . What should be the resistance of shunt to be used ?

The maximum current in a galvanometer can be 10 mA. Its resistance is 10 Omega . To convert it into an ammeter of 1 A, what resistance should be connected in parallel with galvanometer (in 10^(-1)Omega) ?
