Assertion A galvanometer can be used as a voltmeter to measure the voltage across a given section of the circuit. Reason For this it must be connected in parallel with that section of the circuit.

1. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
2. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
3. Assertion is correct but Reason is incorrect
4. Both Assertion and Reason are incorrect

Correct answer: Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Solution

A galvanometer can be converted into a voltmeter by adding a large resistance, allowing it to measure potential difference. A voltmeter is connected in parallel so it measures the voltage across the same two points as the section of the circuit, which is exactly why the assertion is true.
