A galvanometer of resistance \(\mathrm{G} \Omega\) is converted into an ammeter of range 0 to IA. If the current through the galvanometer is \(0.1 \%\) of I A, the resistance of the ammeter is:

  1. \(\frac{\mathrm{G}}{999} \Omega\)
  2. \(\frac{\mathrm{G}}{1000} \Omega\)
  3. \(\frac{\mathrm{G}}{1001} \Omega\)
  4. \(\frac{\mathrm{G}}{100 \cdot 1} \Omega\)

Answer

(B) G 1000
