This question has Statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements.

Statement - I : Higher the range, greater is the resistance of ammeter.
Statement - II : To increase the range of ammeter, additional shunt needs to be used across it.

Options:

Answer:
B
Solution:

For higher range resistance should be less,so statement I is false.

To increase the range by n-times additional shunt should be placedS=Gn-1where 'G' resistance of galvanometer
