If a 100-watt incandescent light bulb puts out 95-watts of heat, what is the efficiency of the bulb? (this is approximately how efficient incandescent light bulbs are!)
In room at 20°C, an incandescent light bulb is using 60 W of electric power. The rate of entropy generated by the light bulb is most closely equal to:
Light bulb A is marked "25 W 120 V" and light bulb B "100 W 120 V"; this means that each bulb converts its respective power when plugged into a constant 120 V source, Find the resistance of each bulb, How long does it take for 1.00 C to pass into bulb A? Is this charge different in any way upon its exit from the bulb versus it entry? Explain, How long does it take for 1.00 J to pass...
Compact fluorescent bulbs are much more efficient at producing light than are ordinary incandescent bulbs. They initially cost much more, but last far longer and use much less electricity. According to one study of these bulbs, a compact bulb that produces as much light as a 100 W incandescent bulb uses only 23.0 W of power. The compact bulb lasts 1.00×104 hours, on the average, and costs $ 11.0 , whereas the incandescent bulb costs only 76.0 ¢, but lasts...

Which device is light produced by electrical discharges through an ionized gas? A. incandescent light bulb B. sodium-vapor lamp C. coils of an electric toaster D. cesium clock
We can reasonably model a 120-W incandescent light-bulb as a sphere 6.5 cm in diameter. Typically, only about 6% of the energy goes to visible light; the rest goes largely to nonvisible infrared radiation. (a) What is the visible-light intensity at the surface of the bulb? W/m2 (b) What are the amplitudes of the electric and magnetic fields at this surface, for a sinusoidal wave with this intensity? Emax = V/m Bmax =
Question 6 5 pts In room at 20°C, an incandescent light bulb is using 60 W of electric power. The rate of entropy generated by the light bulb is most closely equal to: 0.2 W/K 3.0 W/K 0.003 W/K 0 0.0 W/K
Imagine that you turn on the lamp in your room that contains an incandescent light bulb and that you stand 1m from the light. Suppose further that your bulb is rated at 100 W. What is the intensity of the light that passes out through this sphere at this distance of say 1m? Now compare this to a milliwatt laser at the same distance away. How many times more/less intense is the laser beam to your eye compared to the...
