GALVANOMETER as VOLTMETER || video in HINDI

In this Physics video in Hindi for class 12 we explained how a moving coil galvanometer is converted into an voltmeter. This conversion is very easy. The galvanometer is connected to a certain high resistance series combination and hence we get a desired voltmeter.
As a galvanometer can sustain a very small amount of current and hence a small potential difference, by connecting this to a very high resistance may lead to a potential drop and a very small potential difference is found across the galvanometer.
