A galvanometer of resistance `36 Omega` is changed into an ammeter by using a shunt of `4 Omega`. The fraction f of total current passing through the galvanometer is

When a galvanometer of resistance G is shunted with a low resistance S, then the effective resistance R_(eff) of galvanometer becomes R_(eff)=(GS)/(G+S) If current is passed through such a galvanometer, then the major amount of current flows through shunt and the rest through galvanometer, i.e., the current divides itself in the inverse ratio of resistance. Read the above passage and answer the following questions: (i) Why is the resistance of shunted galvanometer lower than that of shunt? (ii) A galvanometer of resistance 30Omega is shunted by a resistance of 3Omega . What fraction of the main current passes (i) through the galvanometer and (ii) through the shunt? (iii) What are the basic values you learn from the above study?

A resistance of 4 Omega is connected in parallel to a galvanometer of resistance 396 Omega . Find the fraction of the total current passing through the galvanometer and the fraction of the total current passing through the shunt.
