Entry from US English dictionary
A unit of electrical power equal to the product of one volt and one ampere and equivalent to one watt of direct 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.
- A powerful PC server loaded with disk and tape drives might require 1,000 volt-amperes or more.
