One of the mysteries of the English language finally explained.
A unit of electrical power equal to the product of one volt and one ampere and equivalent to one watt of direct current.
- ‘Choke input filters are generally not cost effective below 1000 VA (volt-amperes).’
- ‘Apparent power is conventionally expressed in volt-amperes since it is the simple product of rms voltage and current.’
- ‘Neither should be considered more basic than the other, however, and the volt-ampere equations must be so thoroughly learned that they can be used with equal facility in either form.’
- ‘Reactive volt-amperes are a measurement of the wattless, non-useful power.’
- ‘For permanently connected appliances rated at not over 300 volt-amperes or 1/8 hp, the branch-circuit overcurrent device shall be permitted to serve as the disconnecting means.’
- ‘The calculated load required for sizing feeder conductors in this example is 15,625 volt-amperes.’
- ‘A single piece of equipment consisting of a multiple receptacle comprised of four or more receptacles shall be calculated at not less than 90 volt-amperes per receptacle.’
- ‘A powerful PC server loaded with disk and tape drives might require 1,000 volt-amperes or more.’
