Question

The net resistance of an ammeter should be small to ensure that:

• A. it does not get overheated
• B. it does not draw excessive current
• C. it can measure large currents
• D. it does not appreciably change the current to be measured

Hint:

Ammeter resistance should be very low so that it does not significantly change the current in the circuit.

Answer 1

The Correct Option is D

Step 1: Understanding the function of an ammeter.
An ammeter is used to measure current, and it is connected in series with the circuit. To avoid altering the current in the circuit, the ammeter's resistance should be as small as possible.

Step 2: Conclusion.
The correct answer is ( because a small resistance ensures that the ammeter does not significantly affect the current it is measuring.
