As discussed in-

Required shunt -

s= \frac{i_{g}G}{(i-i_{g})}

- wherein

i_{g}- Current through galvanometer

 

 The answer follows from basic Principle of stunt and its use to make an ammeter:

s=\frac{I_{g}}{I-I_{g}}


Option 1)

Statement - I is false, Statement - II is true.

 

This option is correct.

Option 2)

Statement - I is true, Statement - II is true, Statement - II is the correct explanation of Statement - I.
