To convert a galvanometer into a voltmeter, one should connect a

1. High resistance in series with galvanometer
2. Low resistance in series with galvanometer
3. High resistance in parallel with galvanometer
4. Low resistance in parallel with galvanometer

Correct answer: High resistance in series with galvanometer

Solution

A voltmeter is connected in parallel and must have very high resistance so that it draws negligible current. This is achieved by connecting a high resistance in series with the galvanometer.
