If a 4000 watt oven is on for 5 hours, then how many kilowatt-hours (kw-hrs) of energy are used?
Solution: We are given that the oven is 4000 watt and it is on for 5 hours.
We have to find the how many kilowatt-hours (Kw-hrs) of energy are used by the oven.
We first need to convert watts into kilowatt's. We know that:
Therefore, 4000 Watts
Now, we can find how many kilowatt-hours (Kw-hrs) of energy are used by the oven.
Energy used by the oven Kw-hrs
Therefore, 20 kilowatt-hours (kw-hrs) of energy are used by the oven.
