Assertion : An ammeter is always connected in series whereas a voltmeter is connected in parallel.
Reason : An ammeter is a low-resistance galvanometer while a voltmeter is high resistance galvanometer.

Options

A. Assertion is True, Reason is True, Reason is a correct explanation for Assertion
B. Assertion is True, Reason is True, Reason is not a correct explanation for Assertion
C. Assertion is True, Reason is False
D. Assertion is False, Reason is True

Answer

To analyze the given assertion and reason, we will break down the concepts of ammeters and voltmeters, their connections, and their characteristics.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "An ammeter is always connected in series whereas a voltmeter is connected in parallel."
- This is true. An ammeter measures the current flowing through a circuit, and to do this accurately, it must be connected in series with the circuit. A voltmeter measures the potential difference (voltage) across two points in a circuit, and it must be connected in parallel to measure this difference accurately.

2. **Understanding the Reason**:
- The reason states that "An ammeter is a low-resistance galvanometer while a voltmeter is a high-resistance galvanometer."
- This is also true. An ammeter is designed to have very low resistance so that it does not significantly affect the current flowing in the circuit. In contrast, a voltmeter is designed with high resistance to ensure that it draws minimal current from the circuit, allowing it to measure voltage without altering the circuit's behavior.

3. **Conclusion**:
- Both the assertion and the reason are true.
- The reason correctly explains why the assertion is true.

4. **Final Answer**:
- The correct option is: Assertion is true, Reason is true, and the reason is a correct explanation of the assertion.
