Question

A 4000 watt dryer will use 8000 watts if used continuously for 2 hours.
True
Or False

Answer 1

False (?) -- see below

Explanation:

The wording on the question is confusing.

A kilowatt is a measure of how much power an electric appliance consumes, so the dryer uses 4000 watts ( 4 kW) of power.

The energy the dryer uses is 4 kW x 2 hr = 8 kWh (kiloWatt-hours)

So, I would answer the question as False, because of the confusion with the units. If the question said 8000 watt-hrs, I would answer True.

I would complain to the teacher about this question!
