Calculate the Power of a Common Household Dryer

What is the power provided by a 240 volt, 30 ampere common household dryer?

A) 80W

B) 220W

C) 840W

D) 7200W

Answer

The correct answer is D) 7200W

When calculating the power provided by a common household dryer that operates on a 240-volt, 30-amp circuit, you multiply the amperage by the voltage. In this case, it would be 30 amps x 240 volts = 7200 watts.

So, the correct power provided by a 240 volt, 30 ampere common household dryer is 7200 watts. This calculation is crucial in understanding the electrical requirements of appliances to ensure they are connected to the appropriate circuit for safe operation.
