Suppose the cost of an incandescent bulb is 28 cents and that electricity costs 10.5 cents/kWh. Compact fluorescent lightbulbs (CFL), while they are more expensive, use 1/10 of the power for the same amount of illumination. What would be the maximum cost (in dollars) of a CFL such that the total cost (investment plus operating) would be the same for both CFL and incandescent 60 W bulbs? Assume both lightbulbs run for 1000 h.

Electrical Heating Unit

The conversion of electrical energy to heat energy is known as electric heating. The heating system that converts the electrical energy to heat energy for various application is called electrical heating unit. Electricity is employed as the firing mechanism in electric heating systems, which transforms electric current to heat. Electric heaters have heating elements in the form of electric resistors.
