Question

Assertion : The resistance of a milliammeter is greater than that of ammeter
Reason : Shunt resistance in case of a milliammeter is more than that of ammeter

• A. Both (A) and (R) are true and (R) is the correct explanation of A.
• B. Both (A) and (R) are true but (R) is not the correct explanation of A.
• C. (A) is true but (R) is false
• D. (A) is false but (R) is true

Answer 1

Answer: (A)

Both (A) and (R) are true and (R) is the correct explanation of A.

Unlike voltmeter, to have a more accurate reading in the ammeter. The whole current should pass through the ammeter for which the shunt resistance should be much high.
$\therefore$ The resistance of milliammeter is more than just ammeter.
