Core TradesCâu 80 / 700
CALCULATION: A single-phase load draws 24 amperes at 240 volts. What is the apparent power in kilovolt-amperes (kVA)?
a.2.4 kVA
b.4.8 kVA
c.5.76 kVA
d.10.0 kVA
Giải thích
Apparent power = volts x amperes = 240 x 24 = 5,760 VA = 5.76 kVA. Answer 2.4 divides incorrectly; 4.8 uses 200 V or halves; 10.0 uses wrong values.
