Question

It seems hard to justify spending $4.00 for an LED
lightbulb when an ordinary incandescent bulb costs
$0.50. To see if it makes sense, compare a 60 W
incandescent bulb that lasts 1000 hours to a 10 W
LED bulb that lasts 20,000 hours. (These are
typical values.) Both bulbs produce the same
amount of visible light and are interchangeable.

- Part A
If electricity costs $0.15/kWh, about the national average, what is the total cost--purchase price plus energy cost--to
obtain 20,000 hours of light from the incandescent bulb? This is called the life-cycle cost.
Express your answer in dollars.

Given that V= J/A-s and 1 Kwh = 3.6x106 J, what does it cost to operate a window-type air conditioning for one hour if the unit requires a 10-Amp current at 110V and electric energy costs 5 cents per kWh? Compute the cost at 5.0 cents/Kwh of operating an electric motor that takes 15 Amp at 110V.
The pedestrian crossing of Washington Road and Ivy Lane (near the Physics building) needs a back-up battery in event of power failure. In order for the three lights to be bright enough to be seen in daylight, each of the three RL = 50 N lights must dissipate P = the 3 lights are connected in parallel (see the drawing), and the open circuit voltage of the battery (that is, the voltage when there is no current) is Vo = 110 volts.

How much could you pay to replace a 60 W incandescent light bulb with a 15 W compact fluorescent bulb if electricity in your area costs 10 cents per kilowatt hour and you paid 25 cents for the incandescent bulb? You estimate that you will break even after about 1000 hours.
Compact fluorescent tubes cost $15 each and have an estimated life span of 8,000 hours. These tubes consume 20 W of power, but produce illumination equivalent to that of 75 W incandescent bulbs. These cost $3.75 each and have an estimated life span of 1,200 hours. If a home has, on average, six 75W incandescent bulbs on constantly and energy costs $0.2875 per kilowatt-hour, how much money will a consumer save each year by installing fluorescent tubes instead?
