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

A galvanometer acting as a voltmeter will have : (2004)
A high resistance in series with its coil
A low resistance in parallel with its coil
A low resistance in series with its coil
A high resistance in parallel with its coil

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 constructed by connecting a very high resistance in series with a galvanometer coil to measure potential difference safely.
