1.	The resistance of a pivoted type galvanometer is `8Omega` and current for full scale deflection on it is `001A`. This galvanometer is to be converted into an ammeter of `5A` range. The only shunt available is `002Omega`. Find the value of R to be connected in series with the galvanometer coil, figure.
Answer» Correct Answer - `198Omega` `I_g(G+R)=(I-I_g)S` or `001(8+R)=(5-001)002=499xx002` or `R=(4.99xx0.02)/(0.01)-8=9.98-8` `=1.98Omega`
