tungsten filament!!

The melting point and resistivity of tungsten are very high. It does not burn very easy at a high temperature. The electric lamps glow at very high temperatures. Hence, tungsten is mainly used as heating element of electric bulbs.

I hope, this will help you___❤❤

Answer 2

Answer:

C) No filament

A single pin at each end of the tube identifies these tubes, which have no filaments. CFLs are incredibly adaptable and can be utilized in any situation where conventional lights would typically be used. You can use them for recessed fixtures, table lamps, track lighting, or ceiling lighting because they are available in a variety of sizes and styles. There are also 3 CFLs and dimmable CFLs available.

Explanation:

Fluorescent lamps, on the other hand, contain a combination of gases that are contained in a tube. To produce ultraviolet (UV) light, electrical current passes through this tube in place of an included with. Since UV light is invisible to humans, a specific phosphor coating is used to transform it into light that can be seen.

Light is produced via gas interactions inside the tubes of compact fluorescent lamps (CFLs). A CFL light bulb's folding tube contains argon and mercury vapour, while the interior of the tube is painted with luminous ink. To excite the gases, the internal ballast system runs a voltage through to the tube.

Compared to fluorescent, fluorescence or CFL bulbs use less energy, although not as little energy as LEDs. CFLs typically last 8,000 hours on average, whereas LEDs have a 25,000-hour lifetime.
