Frequently Asked Questions
-
What does volt ampere measure?
-
Volt ampere is a unit of apparent power in AC circuits calculated as the product of root-mean-square voltage and current, representing total delivered power.
-
Why convert volt ampere to Btu (th)/hour?
-
Converting volt ampere to Btu (th)/hour translates electrical apparent power into thermal power units useful for HVAC and heating system specifications.
-
Does this conversion consider power factor?
-
No, the conversion does not account for power factor or differences between apparent and real power, which may affect precise calculations.
Key Terminology
-
Volt ampere (VA)
-
Unit of apparent power in AC circuits, equal to RMS voltage multiplied by RMS current, representing total power delivered without power factor consideration.
-
Btu (th)/hour
-
A unit measuring thermal power as the rate of heat transfer equal to one thermochemical British thermal unit per hour.
-
Apparent power
-
Total power in an AC electrical system combining real and reactive power, expressed in volt ampere.
-
Power factor
-
Ratio of real power to apparent power in AC circuits indicating efficiency in power usage.
