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

  1. AStatement- I is true, Statement- II is false.
  2. BStatement- I is false, Statement- II is true.
  3. CStatement- I is true, Statement- II is true, Statement- II is the correct explanation of Statement- I .
  4. DStatement- I is true, Statement- II is true, Statement- II is not the correct explanation of Statement- I .

Correct answer

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

Step-by-step solution

For higher range resistance should be less,so statement I is false. To increase the range by n-times additional shunt should be placed S = G n - 1 where 'G' resistance of galvanometer
