- An evening meal is being prepared in a home kitchen containing an electric oven and a microwave oven. The cost for electricity in the home's neighborhood is $0.15 per kilowatt hour. The microwave oven is specified as a 1000 watt unit, while the oven requires 240 volts and uses a current of 30 amperes to cook at 350 degrees Fahrenheit. A frozen meal can be cooked in the microwave oven set on full power in 10 minutes. The same frozen meal cooked in the electric oven set for 350 degrees F takes 40 minutes.
