Measuring Devices ( Galvanometer, Voltmeter and Ammeter & Meter Bridge ): Practice Problem & Solution

To convert a galvanometer into a voltmeter one should connect a: (2002)
High resistance in series with galvanometer
Low resistance in series with galvanometer
High resistance in parallel with galvanometer
Low resistance in parallel with galvanometer

Solution Explained:

To solve this problem, we apply the core principles of Measuring Devices ( Galvanometer, Voltmeter and Ammeter & Meter Bridge ). Understanding the underlying formula is key to arriving at the correct answer below:

A voltmeter is formed by connecting a very high resistance in series with a galvanometer to measure large potential differences.
