Some Specifics of Power/Energy
Measurements
• Real power, P, or active
power:[1] watt (W)
• Reactive power, Q: voltampere reactive (var)
• Complex power, S: voltampere (VA)
• Apparent power, |S|: the
magnitude of complex
power S: volt-ampere
(VA)
• Phase of voltage relative
to current, φ

Apparent Power – |S| =
Vrms * Irms
• Real (Active) Power – P =
|S| * cos(φ)
• Reactive Power Q=
|S| * sin(φ)
