A balanced 208-volt three-phase load draws 20 amperes. Using 1.732, what apparent power does it use?
- A208 volt-amperes
- Approximately 7,205 volt-amperes
- C4,160 volt-amperes
- D12,480 volt-amperes
Why B is correct
Balanced three-phase apparent power is 1.732 times line voltage times line current. Multiplying 1.732 by 208 volts by 20 amperes gives approximately 7,205 volt-amperes.
