How does light from a flashlight travel?
A flash light generally makes light using a light bulb, which contains a filament. The filament is typically made from tungsten. It is very thin, but capable of withstanding extremely high temperatures. Electricity, from an internal power source, is passed through the filament. The filament has a resistance, so the current creates a very large heat in the wire. Because the wire is so thin, it heats up very quickly, and this excess energy is given out as light, and heat.
What type of light build glows when a filament inside it gets hot?
Electric lamps having incandescent filaments.
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)
How does the indecent light bulb look like?
The incandescent light bulb typically has a glass bulb that is clear or frosted, with a rounded shape. It contains a tungsten filament that glows when electricity passes through it, producing a warm, yellowish light. The base of the bulb is usually made of metal and designed to fit into standard light sockets. Overall, it has a classic and familiar appearance, often associated with traditional lighting.
Can you give me 2 fact about the incandescant light bulb?
-It's a very old technology quickly being replaced by newer more efficient technologies. -The light produced in the bulb is created by electricity heating up a filament inside the bulb creating light. This wouldn't be possible without the bulb however, since oxygen would quickly end this reaction of the filament through oxidation.
What happens to the filament when light bulbs blows?
The filament breaks.
What happens if the filament breaks?
If the filament in a light bulb breaks, the circuit is interrupted and the light bulb will no longer illuminate. This is because the broken filament is unable to produce light when electricity flows through it.
Why does current stop flowing in a light bulb when the filament breaks?
When the filament in a light bulb breaks, the circuit is interrupted and there is no longer a complete path for the current to flow. Without a continuous path for electricity to follow, the current stops flowing and the light bulb stops working.
Why do light bulbs burnout?
For incandescent lights, they operate with a superheated filament. The filament slowly burns away and eventually breaks, opening the electrical circuit.
What will happen if the tiny wire in a light bulb breaks?
If the tiny wire in a light bulb breaks, the circuit will be interrupted and the light bulb will stop working. The wire, called a filament, is responsible for producing light when electricity passes through it. Without the filament intact, the bulb cannot generate light.
What is light bulb filament?
A light bulb filament is a thin wire, typically made of tungsten, that is heated by an electrical current to produce light. As the filament heats up, it glows and produces light, making it a critical component in an incandescent light bulb.
Why it happens that when electric bulb heats up it does not glow?
When an electric bulb heats up, it can stop glowing if the filament inside breaks due to the extreme temperature. The filament in a light bulb glows when an electric current passes through it, but if it breaks, the circuit is disrupted and the bulb will not light up. This can also happen if the filament is damaged by vibration or stress.
Will the bulb light if the filament is broken Why?
No, the bulb will not light if the filament is broken because the filament is the part of the bulb that creates light when electricity passes through it. Without a functioning filament, there is no source of light in the bulb.
Which material is used in the bulbs for the filament?
The filament in traditional incandescent light bulbs is typically made of tungsten. Tungsten has a high melting point and is able to emit light efficiently when heated by an electric current.
What happens to the metal filament of a light bulb after it blows?
After a light bulb blows, the metal filament usually breaks due to the heat and stress it endured during operation. The broken pieces may remain inside the bulb or fall to the bottom, depending on how it fails.
Why doesn't a bulb work when the filament inside it is broken?
A bulb doesn't work when the filament inside is broken because the filament is the component that allows electric current to flow through the bulb. When the filament breaks, it creates an open circuit, preventing electricity from completing the path and reaching the light-emitting part of the bulb. Without the flow of current, the bulb cannot produce light.
What is the purpose of the filament in a light bulb with filament?
The purpose of the filament in a light bulb is to produce light when electricity passes through it, causing it to heat up and emit light.
