Vvolts

VAC volts alternating current

VDC volts direct current

Verror voltage error

VI virtual instrument—(1) a combination of hardware and/or software

elements, typically used with a PC, that has the functionality of a classic

stand-alone instrument (2) a LabVIEW software module (VI), which

consists of a front panel user interface and a block diagram program

Vrms volts, root mean square value

waveform shape the shape the magnitude of a signal creates over time

working voltage the highest voltage that should be applied to a product in normal use,

normally well under the breakdown voltage for safety margin
