Скачать или смотреть Conversion of galvanometer into voltmeter [Hindi] | Moving Charges and Magnetism | Class 12 |Physics

To convert a moving coil galvanometer to a voltmeter, we add a high series resistance, but why?. The high resistance causes most of the voltage to drop across it, leaving a small voltage drop across the galvanometer. This also ends up making the voltmeter have very high resistance. Ideal voltmeters have infinite resistance.
