If a motor draws 6 A at 230 V, what is the electrical input power in watts?

• A. 600 W
• B. 1000 W
• C. 1380 W
• D. 1700 W

Answer: (C)

Electrical power input is found by multiplying voltage by current. With 230 V and 6 A, the input power is 230 × 6 = 1,380 watts. This value represents the electrical power going into the motor; the actual mechanical output would depend on efficiency and losses. The other numbers would correspond to different current levels at 230 V (for example, 600 W would need about 2.6 A, 1000 W about 4.3 A, and 1700 W about 7.4 A). Since the motor draws 6 A, the input power is 1,380 watts.
