A single motor drawing 2 A at 240 V consumes how much power?

• A. 120 W
• B. 960 W
• C. 240 W
• D. 480 W

Answer: (D)

Power is the rate at which electrical energy is used, found by multiplying voltage by current: P = V × I. A motor drawing 2 A from a 240 V supply uses P = 240 × 2 = 480 watts. This is the electrical power it consumes (input power). The motor’s mechanical output would be less than this due to losses from inefficiency, so the actual useful work is smaller than 480 W depending on the motor’s efficiency.
