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:
- \(\frac{\mathrm{G}}{999} \Omega\)
- \(\frac{\mathrm{G}}{1000} \Omega\)
- \(\frac{\mathrm{G}}{1001} \Omega\)
- \(\frac{\mathrm{G}}{100 \cdot 1} \Omega\)
Answer
(B) G 1000
