Which of the following is equal to 2.1kW?

Understanding the relationship between kilowatts (kW) and watts is essential in electrical theory and applications. Kilowatts are a metric unit of power equal to 1,000 watts. Therefore, to convert kilowatts to watts, you multiply the number of kilowatts by 1,000.

In this case, converting 2.1 kW to watts involves multiplying 2.1 by 1,000:

2.1 kW × 1,000 = 2,100 watts.

So, 2.1 kW is equivalent to 2,100 watts, making the correct answer 2100 watts. This demonstrates the proper unit conversion, reinforcing the foundational knowledge of electrical power measurements.
