Refrigeration & Air Conditioning Mechanic Red Seal · Question
A 230V, 1.5 kW single-phase hermetic compressor motor draws 9.5 A of current when operating. The power factor is approximately 0.85. What is the apparent power drawn by the motor?
Apparent power (kVA) is calculated as Voltage (V) multiplied by Current (A), divided by 1000 for kilowatts. So, 230 V * 9.5 A = 2185 VA, which converts to 2.185

Question: A 230V, 1.5 kW single-phase hermetic compressor motor draws 9.5 A of current when operating. The power factor is approximately 0.85. What is the apparent power drawn by the motor?
Answer options: ✅ 2.185 kVA.
- 1.67 kW.
- 1.5 kW.
- 1.275 kVAR.
Correct answer: 2.185 kVA.
Explanation: Apparent power (kVA) is calculated as Voltage (V) multiplied by Current (A), divided by 1000 for kilowatts. So, 230 V * 9.5 A = 2185 VA, which converts to 2.185 kVA. The real power (kW) and power factor are given but are distractors for apparent power calculation.
