Question 1
A balanced 480-volt, three-phase load draws 72 amperes at a lagging power factor of 0.86. What is the real power of this load?
Correct Answer:
51.5 kW
Question 2
A 120-volt, single-phase, 2-wire branch circuit supplies a 16-ampere load. The one-way conductor length is 100 feet of 12 AWG copper (K = 12.9, area = 6,530 CM). What is the calculated voltage drop?
Correct Answer:
6.32 volts
