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.
(a) How much energy does it take to cook the frozen meal in the microwave at full power and how much does it cost?
(b) How much energy does it take to cook the frozen meal in the electric oven at 350 degrees Fahrenheit and how much does it cost?

An electrical substation had a sudden discharge arc event lasting 0.005 seconds. The event produced 768,000 volts that conducted 500 amperes to a nearby grounded metal strap and opened a 500 ampere protective breaker.
(a) How much power was produced by the electrical discharge?
(b) How much energy was in the discharge?
(c) How long could a 75 watt light bulb stay lit, if all the energy in the arc was used to operate it?
