Description: This is the circuit connection for converting a galvanometer into a voltmeter. In this circuit, high resistance should be connected to the galvanometer in series and a voltmeter should also be connected to the resistance+galvanometer series arrangement. We have used a resistance box to provide the high amount of resistance required for the conversion of the galvanometer into the voltmeter.

Connect your circuit components carefully. Ammeters can be easily damaged! I guess if you connect your voltmeter wrong, you'll just get bad readings. And stop saying "ampmeter." It sounds like you're multiplying current times distance. Pshaw.

Why do you want to convert a Galvanometer into a Voltmeter? You want to measure large voltages and do not want to blow the Galvanometer. Short and Simple explanation.
