Positioning the wire in concentric loops amplifies this field. If you've read How Electromagnets Work, you know that when you send electrical current through a wire, it generates a magnetic field. A basic inductor consists of a coil of wire in a circuit, which may be wound around a piece of metal. The simplest sort of ballast, generally referred to as a magnetic ballast, works something like an inductor. Because the naked eye cannot perceive ultraviolet light, it is converted to visible light by the phosphor coating.įor more information about how lightbulbs work, contact Pacific Lamp.A fluorescent lamp's ballast works to control this. When the lamp is flicked on, electrons are bombarded into the ionized mixture of gases and ultraviolet radiation is created. The tube is layered with a substance made out of phosphorus. The components of a fluorescent lamp include a sealed glass tube containing a mixture of mercury and nonreactive gases, such as neon, xenon, argon and krypton. The emitted lightĪppears yellowish, and a significant portion of energy is lost as heat.

The tungsten wire, the filament's temperature reaches around 3,140 to 4,940 degrees Fahrenheit. When a supply of electrical current passes through Or infused with an inert gas that prevents it from burning up. In most households, the two commonly used types of light fixtures are incandescent bulbs and fluorescent lamps.Īn incandescent bulb consists of a tungsten metal filament inside a sealed glass bulb, which is either evacuated
