Compact fluorescent bulbs are much more efficient at producinglight than are ordinary incandescent bulbs. They initially costmuch more, but last far longer and use much less electricity.According to one study of these bulbs, a compact bulb that producesas much light as a 100 W W incandescent bulb uses only 23.0 W W ofpower. The compact bulb lasts 10000 hours, on the average, andcosts $ $ 11.00, whereas the incandescent bulb costs only $ $ 0.75,but lasts just 750 hours. The study assumed that electricity cost $$ 0.070 per kilowatt-hour and that the bulbs were on for 4.0 h perday.
a.What is the total cost (including the price of the bulbs) torun incandescent bulbs for 3.0 years
b. What is the total cost (including the price of the bulbs) torun compact fluorescent bulbs for 3.0 years?
c.What is the resistance of a \"100 WW\" fluorescent bulb?(Remember, it actually uses only 23 WW of power and operates across120 VV.)
