For this purpose connect a low resistance S in parallel with Galavanometer (G). Hence total current I is divided into G and I-Ig through S
In parallel combinaton Voltage is same
IgXG=(I-Ig)XS
G=resistance of galvanometer=98
Ig=2% of I=2I/100=.02I
IgXG=(I-Ig)XS
S=IgXG/(I-Ig)=(0.02IX98)/(I-.02I)=2
That is when we connect 2 in parallel with galvanometer, 2% of current passes through it
