Question:
How can we convert a moving coil galvanometer into a voltmeter?
Options:
By introducing a low resistance in series
By introducing a high resistance in series
By introducing a high resistance in parallel
By introducing a low resistance in parallel
Correct Answer:
By introducing a high resistance in series
Explanation:
Moving-coil galvanometer can be converted into a voltmeter by increasing its effective resistance by connecting a high resistance in series with the galvanometer. The series resistance protects the meter and increases the range of the meter.
