Electricity what does va stand for

The energy consumed is related to the resistance in an electrical circuit. An example of consumed energy is the filament in a light bulb.

Reactive power measured in VAR or voltamps reactive is the portion of power flow due to stored energy. An example of stored energy is a charged flash bulb in a camera. Apparent power measured in VA or voltamps is a mathematical combination of real power and reactive power. Apparent power measured in VA or voltamps is a mathematical combination of real power and reactive power. The geometric relationship between apparent power, reactive power and real power is illustrated in the power triangle below:.

Mathematically, real power watts is related to apparent power VA using a numerical ratio referred to as the power factor PF , which is expressed in decimal format and always carries a value between 0 and 1.

For many newer types of IT equipment, such as computer servers, the typical PF is 0. For legacy personal computers PCs , this value can be 0. Onsite Service Need someone to replace the batteries or install new equipment, we can help with service providers in every capital city read more.
