Textbook Question
Chapter 1, Problem 3P
A typical discounted price of a AAA battery is $0.75. It is designed to provide 1.5 volts and 1.0 amps for about an hour. Now we multiply volts and amps to obtain power of 1.5 watts from the battery. Thus, it costs $0.75 for 1.5 Watt-hours of energy. How much would it cost to deliver one kilowatt-hour? (Think of a kilowatt-hour of electricity as the power needed to run your dishwasher one time.) How does this compare with the cost of energy from your local electric utility at $0.10 per kilowatt-hour? (1.2 1.3)
