An incandescent lightbulb draws 590 mA, while an LED with the same light output draws 91.7 mA. Both operate on standard 120-V household power.

Part A

Determine the energy-consumption rate of the incandescent lightbulb.

Part B

Part complete

Determine the energy-consumption rate of the LED.

Part C

Suppose you've been operating the incandescent bulb for 3 hours a day and that your electrical energy costs 14.2 ¢/kWh¢/kWh. How much money will you save on your electric bills over a year if you replace the incandescent with the LED? Note that an incandescent lightbulb costs about $1, while you might pay $5 for an LED—and the LED will last many years.

Express your answer in dollars.

A new LED light to replace incandescent bulbs has come on the market. The box says it has an average life of 9,000 hours with a standard deviation of 300 hours. a) What is the probability that a single bulb will last between 8950 and 9100 hours? b) What is the probability that the mean of a sample of 70 bulbs picked at random will be between 8950 and 9100 hours?

The city of Metropolis is considering replacing incandescent bulbs in traffic lights with light-emitting diode (LED) lights because they use significantly less energy and last much longer without abrupt failure. Currently Metropolis has 80,000 incandescent bulbs in traffic lights at approximately 12,000 intersections. It is estimated that replacing all the incandescent bulbs with LED will cost $46.02 million. However, the investment is also estimated to save the city $8.85 million per year in energy costs.

A 15W compact fluorescent lamp (CFL) provides the same light as a 60W incandescent lamp. Electricity costs the end user 10 cents per kW-hr. a. If an incandescent lamp costs 60 cents and the CFL costs $2, what is the "payback" period? b. Over the 9000-hr lifetime, what would be saved in carbon emissions? (280 g carbon emitted per kW-hr) c. At a (proposed) carbon tax of $50/tonne, what is the equivalent dollars saved as carbon emissions? (1 tonne =...
