1. A bike light lasts 10 hours and consumes 1 Watt of power. What is the capacity rating of the battery, in Coulombs? What is the electrical cost to operate this light for 10 hours? You can use any rating of the light used in bike, it just has to make sense.
2. What costs more, a package of top ramen or the heat to cook the top ramen with an electrical stove or hotplate?
3. What is the cost to drive an electric car 100 miles? How many miles would have to be driven for an electric car of your choice to equal the cost of a conventional gas car of your choice?
4. How much does the electricity cost to binge watch the entire series of "The Office" on a laptop or desktop computer. Season 5 of "The Office" had 9 million estimated viewers. How much coal would it take to generate the electricity for 9 million viewers to watch the entire series of "The Office"?
NOTE: YOU ARE ALLOWED TO USE ANY COST FOR THE QUESTIONS, IT JUST HAS TO MAKE SENSE.
Explanation / Answer
1) capacity rating of the battery = 10 * 1
= 0.01 kWh
the electrical cost to operate this light for 10 hours = 10 * 3600 * 0.001
= $ 36
2) heat to cook the top ramen with a hotplate costs more .
3) cost to drive an electric car 100 miles = 100 * 3.5 * 0.05
= $ 17.5
4) the electricity cost to binge watch the entire series = 9 * 5 * 0.5
= $ 22.5
