Which of the following statements is wrong?
Which of the following statements is wrong?
Show Hint
A voltmeter is always connected in parallel, while an ammeter is always connected in series with the component being measured.
Updated On: Apr 22, 2026
- Voltmeter should have high resistance
- Ammeter should have low resistance
- Ammeter is placed in parallel across the conductor in a circuit
- Voltmeter is placed in parallel across the conductor in a circuit

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the function of a voltmeter and ammeter.
- A voltmeter measures the potential difference between two points in a circuit. It is always connected in parallel with the component across which the voltage is to be measured. Therefore, it must have high resistance to prevent it from drawing excessive current.
- An ammeter measures the current passing through a component. It must be connected in series with the component, and it must have very low resistance to avoid altering the current.
Step 2: Identifying the incorrect statement.
- Statement (1) is correct: A voltmeter must have high resistance.
- Statement (2) is correct: An ammeter should have low resistance.
- Statement (3) is incorrect: An ammeter is always placed in series with the conductor, not in parallel.
- Statement (4) is correct: A voltmeter is placed in parallel across the conductor.
Step 3: Conclusion.
The wrong statement is (3), as the ammeter should be placed in series with the conductor.
