Interview Question in Voltage, Current, and Power

Interview Question :: The measured average power, current, and voltage in a circuit are 880 W, 5 Arms and 220 Vrms Determine

The measured average power, current, and voltage in a circuit are 880 W, 5 Arms and 220 Vrms , respectively. Determine the following. Phase angle ? =? power factor cos ? =? and apparent power Papp = ?

Answers to "The measured average power, current, and voltage in a circuit are 880 W, 5 Arms and 220 Vrms Determine"

RE: The measured average power, current, and voltage in a circuit are 880 W, 5 Arms and 220 Vrms Determine?
power apparent=VI; V=220v, I=5A==> Papp= 5*220= 1100W . P=VIcos@; where cos@ is power factor 880=1100cos@; ==> cos@=880/110=0.8; @=cos^-1 (0.8)=36.86 degrees.
