This question has Statement I and Statement II.

Question:

This question has Statement I and Statement II. Of the four choice 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.

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

  2. Statement-I is true, Statement-II is true, Statement-II is not the correct explanation of Statement-I.

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

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

Correct Option: , 4

Solution:

To increase the range of ammeter, resistance should be decreased (So additional shunt connected in parallel) so total resistance to ammeter decreases.
