Question:
The resistance of an ideal ammeter is:
The resistance of an ideal ammeter is:
Show Hint
Ideal Ammeter R = 0; Ideal Voltmeter R = $\infty$.
Updated On: Apr 8, 2026
- zero
- infinite
- small but non-zero
- large
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
An ammeter is connected in series to measure current.
Step 2: Analysis
To ensure it does not change the circuit's total resistance and the current it aims to measure, it must have no resistance of its own.
Step 3: Conclusion
The resistance of an ideal ammeter is zero.
Final Answer: (A)
