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.

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.
