Question

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.

• A. Statement - I is true, Statement - II is true, Statement - II is the correct explanation of Statement-I
• B. Statement - I is true, Statement - II is true, Statement - II is not the correct explanation of Statement-I
• C. Statement - I is true, Statement - II is false
• D. Statement - I is false, Statement - II is true

Answer 1

Answer: (D)

For Ammeter, $S =\frac{ I _{ g } G }{ I - I _{ g }}$
So, for I to increase, S should decrease, so additional $S$ can be connected across it.
