  1. Simple voltmeter is just a resistor in series with the meter movement, or galvo. The range is determined by the resistor value and by the full scale current of the galvo.

    An ammeter is a small value resistor in parallel with the galvo.

    An ohmmeter is a battery and an ammeter in series.
