tin the circuit, or the current through the voltmeter, but thedifference in pressure between the voltmeter terminals. Themovement of its magnetic system, of course, depends uponthe current flowing through the voltmeter, but the scale iscalibrated by applying known E. M.

A voltmetermeasures the current flowing through it, but the calibration isin terms of the pressure causing this current to flow. See Exp 57,11182. 234.
