A Three-Phase Motor Is Connected to a 480V, 60-Hz Line

A three-phase motor is connected to a 480V, 60-Hz line. A clamp-on ammeter indicates a running current of 68A at full load, and a three-phase wattmeter indicates a true power of 40,277W. To solve this problem, first find the amount of apparent power in the circuit using the formula ____.

A) VA = 1.732 / (EL x IL)
B) VA = (EL x IL) / 1.732
C) VA = 1.732(EL + IL)
D) VA = 1.732 x EL x IL
