An electrical filament is a thread of metal, usually tungsten, which is used to convert electricity into light in incandescent light bulbs (as developed in 1874 by Alexander L … odygin and in 1878 by Joseph Wilson Swan, among others), and into heat in vacuum tube devices.ach stamen has 2 parts the stalk, called the filament and the pollen producing organ called the anther. The Filament is the stalk of the anthers. Thin filaments slide past the thick filaments, shortening the sarcomere. The thick and thin filaments do the actual work of a muscle.
Higher-watt bulbs have a bigger filament, so they produce more light. A three-way bulb has two filaments of different wattage -- typically a 50-watt filament and a 100-watt filament. The filaments are wired to separate circuits, which can be closed initially using a special three-way socket. The filament in a light bulb is housed in a sealed, oxygen-free chamber to prevent combustion. In the first light bulbs, all the air was sucked out of the bulb to create a near vacuum -- an area with no matter in it. Since there wasn't any gaseous matter present (or hardly any), the material could not combust.

Best Answer: When the power is switched on, the electrical energy flows through the filament. The resistance provided by the filament makes it heat up and the electrical energy is converted to light and heat energy. The bulb glows and heats up. The Muse.  What is an electrical filament?

Each stamen has 2 parts the stalk, called the filament and the pollen producing organ called the anther. The Filament is the stalk of the anthers. Contracting a Muscle. During contraction, the thin filaments slide past the thick filaments, shortening the sarcomere. The thick and thin filaments do the actual work of a muscle, and the way they do this is pretty cool. Thick filaments are made of a protein called myosin. At the molecular level, a thick filament is a shaft of myosin molecules arranged in a cylinder. Thin filaments are made of another protein called actin In many types of cells, networks of actin filaments are found beneath the cell cortex, which is the meshwork of membrane-associated proteins that supports and strengthens the plasma membrane. Such networks allow cells to hold — and move — specialized shapes, such as the brush border of microvilli. For example, vimentin filaments are found in a broad range of cell types and frequently colocalize with microtubules. Similarly, lamins are found in all cell types, where they form a meshwork that reinforces the inside of the nuclear membrane.
