Final answer:
The load used for calculating power consumption of a clothes dryer is typically the power rating of the dryer, such as 5,000 W which equates to 5 kWh or 18 MJ for one hour of use.
Step-by-step explanation:
The correct answer is that when calculating the total load for a clothes dryer, one typically uses the power rating of the dryer which is often given in watts (W). In the example provided, a 5,000 W clothes dryer is mentioned, which if run for about an hour, will use 5 kWh of energy.
kWh stands for kilowatt-hour and is a unit of energy commonly used to measure electricity consumption. Converting this to megajoules (MJ), this quantity of energy is equivalent to 18 MJ.
If we refer to the information of a person generating power by pedaling, it states that a person in good physical condition can generate about 100 W of power continuously.
Therefore, to run a 4.00-kW clothes dryer, it would take 40 such individuals pedaling in concert (since 4,000 W divided by 100 W per person equals 40).
