A galvanometer having full scale deflection current of $10\mathrm{ }\mathrm{m}\mathrm{A}$ and resistance $8\mathrm{ }\mathrm{\Omega }$ is joined in circuit as shown. When the terminals $A$ and $B$ are used and $C$ remains open, the range of the ammeter is $I.$ When the terminals $A$ and $C$ are used and $B$ remains open, then the range of the ammeter is
