Current Electricity

For designing a voltmeter of range $50 \mathrm{~V}$ and an ammeter of range $10 \mathrm{~mA}$ using a galvanometer which has a coil of resistance $54 \Omega$ showing a full scale deflection for $1 \mathrm{~mA}$ as in figure.





(A) for voltmeter $R \approx 50 \mathrm{k} \Omega$


(B) for ammeter $\mathrm{r} \approx 0.2 \Omega$


(C) for ammeter $\mathrm{r}=6 \Omega$


(D) for voltmeter $R \approx 5 \mathrm{k} \Omega$


(E) for voltmeter $R \approx 500 \Omega$
