Homework Answers
1 Kwhr = 1 kw*1hr
= 1000 W * 3600 s
= 3.6*10^6 J
Answer: 3.6*10^6 J
1 mega joule = 1*10^6 J
= 1*10^6 J / (3.6*10^6 J/jwh)
= 0.278 Kwh
cost = 0.278 kwh * $ 0.09 per kwh
= $ 0.025
Answer: $ 0.025

Energy consumption is measured in units of kilowatt hours (kWh). The more kWh a household use in a month, the higher the energy bill. A power company charges customers $0.12 per kWh for the first 500 kWh. After the first 500 kWh, the rate is $0.15 per kWh. Write a program to calculate energy charge. You must write and use the following two functions. (a) A main function: Ask the user to enter number of kWh used. Call the bill_calculator...

The average US citizen consumes 12000 kWh of electric energy per year an ‘ end use’ number and does not include the energy lost in converting other energy sources, e.g. fossil fuels to electricity. Note also that a kWh (kilowatt hour) is a unit of energy (not power) but a ‘kWh per year’ is a unit of power. The average electric bill indicates that a consumer pays about $0.12 per kWh of electric energy. Your Uncle Joe wants to get...
