A galvanometer having coil resistance $10 \ \Omega$ shows a full scale deflection for a current of $3 \mathrm{~mA}$. For it to measure a current of $8 \mathrm{~A}$, the value of the shunt should be:
  • A $3 \times 10^{-3}\  \Omega$
  • B $4.85 \times 10^{-3} \ \Omega$
  • C $3.75 \times 10^{-3} \ \Omega$
  • D$2.75 \times 10^{-3} \ \Omega$
