How did thomas Edison come up with the invention of the light bulb?
Thomas Edison didn't actually invent the light bulb. Edison just improved it, many other people had invented it only Edison made a more efficient one that lasted longer.
Cancave mirrors are used in car head lights Why?
The light rays come together to make a bright spot of light. When a concave mirror is used in car headlights, a bulb is placed at the spot where light would come together. This has the effect of making the opposite happen. The rays of light shining out from the bulb are reflected off the concave mirror to make a strong beam of light, which travels out in front of the car to shine on the road.
Why CONCAVE MIRRORS USED IN TORCH LIGHT?
The concave mirror reflects the bulb's light, and if the bulb is at the mirror's focus, sends it out as a parallel beam.
How much energy does a led bulb use?
It varies, since they come in different capacities. In general, only a small fraction of what an old-fashioned incandescent light bulb uses; and still quite a bit less than what a fluorescent light uses.
How does a light bulb turn on and off?
First, to explain the on/off switch:There is an electrical wire connected to the switch. When the switch is in the [ON] position, it is called a closed circuit, when electricity can run through to power the light bulb. When the switch is in the [OFF] position, the switch stops touching the wires, and it is called an open circuit, where the circuit is broken and the electricity cannot flow.Second, light bulbs:Normal incandescent light bulbs are powered when an electric current runs through their filament. Incandescent bulbs' filaments are very thin, and when electricity runs through them they become so hot they glow bright yellow to white.How come the filaments don't burn up? That was a problem Thomas Edison came across when he tried to make incandescent light bulbs; the filaments burned up. He solved that problem by making a vacuum inside the bulb - No air means no Oxygen, and no Oxygen means no burning. (vacuum means absolutely no gas or air inside an area.) However, he had to make very thick walls for that style of bulb. Today, we fill incandescent bulbs with non-reactive gas at the same pressure as outside air, so bulb walls can be nearly paper-thin.Please rate this answer! :D
