ter is fixed, it follows by Ohmslaw that the current through the voltmeter will be directly propor-tional to the electromotive force in volts, so that a voltmeter is reallyoperated by variations in current the same as an ammeter. In a voltmeter, the movable coil consists of many turns of finewire… … ilg. 22.

In an ammeter, when designed for small capacity, the total cur-rent to be measured may be passed through the movable coil which iscomposed of a few turns of…
