Tungsten is used as the filament in electric bulbs due to its high melting point (about 3,422°C or 6,192°F) and excellent conductivity. This allows it to withstand the high temperatures generated when an electric current passes through it, producing light without melting. Additionally, tungsten has a low vapor pressure, which helps prolong the filament's lifespan by reducing evaporation at high temperatures.
What else can I help you with?
What is electrical energy converted into when electric current flows through the metal filament of a light bulb?
Electrical energy is converted into light and heat when electric current flows through the metal filament of a light bulb.
When electric current flows through the metal filament of light bulb electric energy is converted to?
Heat and light.
What happens if you put metal in a kettle if it both does and does not touch the metal filament at the bottom of an electric kettle?
If the metal does not touch the filament, it should be safe to use in an electric kettle without causing any damage. However, if the metal comes into contact with the filament, it can create a short circuit, potentially causing damage to the kettle or even a safety hazard like an electric shock or a fire. It's best to avoid putting any metal objects in an electric kettle to prevent any risks.
What element is in an incondescent light bulb filament?
The filament in an incandescent light bulb is typically made of tungsten. Tungsten is a metal with a high melting point that allows it to produce light and heat when an electric current passes through it.
What does a light bulb have to do with an electrical light source?
A light bulb is a source of electric light. In an incandescent light bulb, the glass bulb forms a protective shield around a glowing filament. The air inside the glass bulb is removed, or replaced with an inert gas. Electric current is passed through a thin metal filament (usually tungsten), which causes it to glow white hot, giving out light. The protective bulb stops the filament from burning up, as it has no Oxygen.
When electric currents flow through the metal filament of a light bulb electric energy is converted to?
When electric currents flow through the metal filament of a light bulb, electric energy is converted to light and heat energy. The filament heats up due to the resistance in the metal, eventually producing light as it emits photons.

When electric flows through the metal filament of a high light bulbs what is electric energy transformed too?
Heat and light. The metal filament heats up to the point of incandescence in the visible part of the spectrum.
The metal with the highest melting point for this reason it is often used as the filament in light bulbs?
tungsten
When electric currents flows through the metal filament of a light bulb electrical energy is coverted to?
When an electric current flows through the metal filament of a light bulb, electrical energy is converted to heat and light energy, producing the illumination that we see as light. The filament heats up due to the resistance to the current passing through it, causing it to emit visible light.
When electric energy flows through the metal filament of a light bulb energy is converted to?
Heat, which then produces light.
When electric current flows through the metal filament of a light bulb electrical energy is a?
converted into heat and light energy.
Which transition metal is used in light bulbs as a filament?
Tungsten is the transition metal commonly used in light bulbs as a filament. It has a high melting point and is able to withstand the high temperatures generated by the electric current passing through it, making it ideal for producing light.
How does a electric current flow through a light bulb?
The electrical current comes into the bulb from the metal side,flow through the filament ,and out the tip.
Explain why the filament must be made of metal?
The filament in a light bulb must be made of metal because it needs to have a high melting point to withstand the high temperatures generated by the electric current passing through it. Metals like tungsten are commonly used because they can reach very high temperatures without melting, allowing the filament to emit light.
