Question

Assertion (A) Higher the range, greater is the resistance of ammeter. Reason (B) to decease the range of ammeter, additional shunt needs to be used across it.​

Answer 1

Explanation:

Correct option is

C

Assertion is correct but Reason is incorrect

For Ammeter, S=I−IgIgG

So for I to increase, S should decrease, so additional S can be connected across it.

So the assertion is correct but the reason is incorrect.
