Definition of volt-ampere in US English: volt-amperenoun A unit of electrical power equal to the product of one volt and one ampere and equivalent to one watt of direct current. Example sentencesExamples - A powerful PC server loaded with disk and tape drives might require 1,000 volt-amperes or more.
- 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.
- The calculated load required for sizing feeder conductors in this example is 15,625 volt-amperes.
- 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.
- Choke input filters are generally not cost effective below 1000 VA (volt-amperes).
- 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.
- Apparent power is conventionally expressed in volt-amperes since it is the simple product of rms voltage and current.
- Reactive volt-amperes are a measurement of the wattless, non-useful power.
