Knowledge of quantum physics brings a sense of wonder to the operation of even something as simple as an incandescent light bulb. solar filament galaxy filament the Ursa Major Filament. A chainlike series of cells, as in many algae. When you connect the A battery, the filament of the tube is heated to release negatively charged electrons. Many tubes also have small structures, known as grids, between the filament and the plate. physics, astronomy A massive, thread -like structure, such as those gaseous ones which extend outward from the surface of the sun, or such as those (much larger) ones which form the boundaries between large voids in the universe. Electrons travel through the partial vacuum inside the tube, flowing from the filament to the positively charged plate. The fine metal wire in a lightbulb, which becomes incandescent when heated by an electric current. A bulb has two terminals. n. 1. Add your answer and earn points. Conductor The movement of electron gives rise to the flow of current through metals It may be in the halos around galaxies or, as another paper recently suggested, in filaments stretching between galaxies. The filament of an electric lamp is very fine and therefore offers considerable resistance. ... Ohm's law states that V and I are directly proportional, meaning there is a constant factor of proportionality. If the filament is a cylinder 4.00 cm long (it may be coiled to save space), what is its diameter? We Asked, You Answered. Origin of Filament ...

The American Heritage® Science Dictionary Made of thin (0.2 mm) tungsten wire because tungsten: 1. has a high atomic number (A 184, Z 74) 2. is a good thermionic emitter (good at emitting electrons) 3. can be manufactured into a thin wire 4. has a very high melting temperature (3422°c) 2. Filaments are solar prominences that are viewed against the solar surface rather than being silhouetted along the outer edges of the disk. Give Dan Rhodes a small sample of a novel polymer, and he’ll figure out how to extrude it into a filament, and how to fine-tune the process to see whether the material can be made to work in high-speed manufacturing.
