Question

What is the peak power consumption of a 120-V AC microwave oven that draws 10.0 A?

a) 1200 W
b) 1.20 kW
c) 12.0 W
d) 12.0 kW

Answer 1

The peak power consumption of a 120-V AC microwave oven that draws 10.0 A is 1200 W or 1.20 kW, which corresponds to option (b) in the provided choices.

Step-by-step explanation:

The peak power consumption of a 120-V AC microwave oven that draws 10.0 A can be calculated using the formula for electrical power, which is P = V × I. Here, P is the power in watts (W), V is the voltage in volts (V), and I is the current in amperes (A).

The voltage of the microwave is given as 120 V and the current drawn is 10.0 A. Applying these values to the power formula yields:

P = 120 V × 10.0 A = 1200 W

Converting this to kilowatts (kW), we get:

1200 W ÷ 1000 = 1.20 kW

Therefore, the correct answer is 1.20 kW which corresponds to option (b).
