Uses of tungsten?
Tungsten's many alloys have numerous applications, most notably in incandescent light bulb filaments, X-ray tubes (as both the filament and target), and superalloys. Tungsten's hardness and high density give it military applications in penetrating projectiles. Tungsten compounds are most often used industrially as catalysts.
What is the general resistance of a tungsten filament?
The resistance of the filament in a light bulb is(voltage at which the bulb is designed to operate)2/(the rated power/watts of the bulb)
What is the difference between incandescent and fluorescent light bulbs?
Incandescent lightbulbs have an electrical circuit that passes through a tungsten wire. As the electricity flows, the tungsten is heated up to a point where it emits light waves. Gases (xenon, I think) help sustain the wire until it breaks. This is when the light stops and needs to be replaced. (the tungsten also emits heat when lit) Incandescent lights have the full spectrum of colors. Fluorescent bulbs are filled with a gas and a bit of mercury. Electricity gives the ions in the gas energy, which is released in the form of light. This method sustains the bulb far longer than an incandescent lightbulb. Fluorescents release much less heat, making them more energy efficient. However, the spectrum of the fluorescent bulb is missing a few colors of the spectrum, which makes the spectrum look cool and incredibly weird.A fluorescent lamp or fluorescent tube is a gas-discharge lamp that uses electricity to excite mercury vapor. The excited mercury atoms produce short-wave ultraviolet light that then causes a phosphor coating on the inside of the bulb to fluoresce (glow), producing visible light.
Is tungsten a metal?
yes
Is tungsten carbide and graphite the same element?
Technically no, since an element defines that it is a single atom. Tungsten Carbide is a chemical compound consisting of Tungsten and Carbon (W2C) and Graphite is a form of pure carbon
Suggest the physical property that can render tungsten suitable for making filament of tungsten light bulb?
The high melting point of tungsten (3422°C) is the physical property that makes it suitable for making filaments in tungsten light bulbs. This property allows the filament to reach high temperatures without melting, resulting in the efficient emission of light.
What element is used as a light bulb as a filament?
Usually tungsten.
Why is tungsten used the filament of the bulb?
Tungsten is used in light bulb filaments because it has a very high melting point and does not evaporate easily, allowing it to glow brightly and last longer without burning out. Additionally, tungsten is a good conductor of electricity, making it efficient at converting electrical energy into light.
Which element is used in light bulbs as filment?
Most often it is tungsten.
The element used in light bulbs filaments?
Tungsten is the element most commonly used in light bulb filaments due to its high melting point and ability to produce light efficiently when heated.
What are two properties of the metal tungsten that make it good material for the filament?
Tungsten has a high melting point of 3422°C, allowing it to withstand the high temperatures generated in an incandescent light bulb. Additionally, tungsten is a good conductor of electricity, enabling efficient conversion of electrical energy into light energy in the bulb.
Which element is used in light bulbs as the filament?
Generally, tungsten.
What element is used a light bulb filaments?
Tungsten is the most common today.
What is tungsten bulb?
A tungsten bulb is a common lightbulb, the fillamint in a bulb is the small wire in the middle that's drawn across the two contacts. This wire provides an electrical resistance and heats up and this generates light. In a common lightbulb all the air must be taken out and replaced with an inert gas to stop the tungsten fillament burning away.
What element is used inside light bulbs in the periodic table?
The element used in most light bulbs is tungsten, located on the periodic table with the symbol W and atomic number 74. Tungsten's high melting point and ability to emit bright light when heated make it ideal for light bulb filaments.
What type of gas is in a tungsten-halogen light bulb?
Halogen gas is in a Tungsten-Halogen Light Bulb.
Which is the most energy efficient light source?
LEDs are the most energy-efficient lights as of 2016.
