A balanced 208-volt three-phase load draws 40 amperes at unity power factor. Using 1.732, what real power is used?
- A24.9 kilowatts
- B8.32 kilowatts
- About 14.4 kW
- D5.2 kilowatts
Why C is correct
Balanced three-phase power is 1.732 times line voltage times line current at unity power factor. The result is about 14,410 watts, or 14.4 kilowatts.
