Thomas Edison created such great innovations as the practical incandescent electric light bulb and the phonograph. A savvy businessman‚ he held more than 1‚000 patents for his inventions. 3.Thomas Edison rose from humble beginnings to work as an inventor of major technology. Setting up a lab in Menlo Park‚ some of the products he developed included the telegraph‚ phonograph‚ the first commercially practical incandescent electric light bulb‚ alkaline storage batteries and Kinetograph (a camera for motion

little kick of hand held lights. The principal on which glow sticks work to an everyday person is almost supernatural‚ but in fact the technology used to make it and the way it works is actually very simple indeed. But how does a light stick give off such a strong light source with no bulb and no battery. As a form of energy‚ light can be emitted through a variety of processes. These processes may include 1. Incandescent lighting works through the emission of light due to heat‚ this is the

There are two common meanings of the term "greenhouse effect". There is a "natural" greenhouse effect that keeps the Earth’s climate warm and habitable. There is also the "man-made" greenhouse effect‚ which is the enhancement of Earth’s natural greenhouse effect by the addition of greenhouse gases from the burning of fossil fuels (mainly petroleum‚ coal‚ and natural gas). In order to understand how the greenhouse effect operates‚ we need to first understand "infrared radiation". Greenhouse gases

GENERATED IN APPLIANCES Why do some appliances produce more heat than the others? Most appliances with high power rating are heating appliances.The heating appliances has a heating element like resistors. The resistorsconvert electrical energy into light and thermal energy . It depends on the resistance of material if how much heat can be produced from electricity. Those devices who produced heat‚ the Nichrome wire is an element who is responsible for heating . when we say nichrome wire ‚ it is

LED lamp (or LED light bulb) is a solid-state lamp that uses light-emitting diodes (LEDs) as the source of light. LED lamps offer long service life and high energy efficiency‚ but initial costs are higher than those of fluorescent and incandescent lamps. Chemical decomposition of LED chips reduces luminous flux over life cycle as with conventional lamps. Commercial LED lighting products use semiconductor light-emitting diodes. Research into organic LEDs (OLED)‚ or polymer light-emitting diodes
