Question

How to convert galvanometer to voltmeter?

Answer 1

Hey, there!

Here's your answer.

Connecting a very high resistance(S) in series with a galvanometer (which also has some resistance, say G) would make a voltmeter.

Voltmeters have a very high resistance, that's the reason why they are connected in parallel, so that very less current passes through it.

Now, that we have connected a very high resistance in series with the Galvanometer, the equivalent resistance is very very high, which when connected in parallel would be analogous to Voltmeter.

Hope that helps.

Thanks.
