Why does a magnet make the filament move in a light bulb?
When a magnet is brought near a light bulb, the magnetic field interacts with the electric current flowing through the filament, causing a force to be exerted on the filament. This force can make the filament move or vibrate, resulting in changes in the brightness or flickering of the light bulb.
What make a light bulb glow?
A light bulb glows when an electric current passes through the filament inside, which heats up due to resistance and emits light. The filament is usually made of tungsten, a material that can withstand high temperatures without melting.
Can copper be used to make filament of bulbs?
Well, isn't that a happy little question! Copper can indeed be used to make filaments for light bulbs. Its high melting point and excellent conductivity make it perfect for this purpose. Just imagine all the beautiful light that filament will create, lighting up the world with its warm glow.
How is an electric current flow through the bulb to light it up?
The electrons flow into one end of the metal bulb bottom, they then flow into the filament where they meet heavy resistance. This resistance causes the filament to heat up and produce light as the electrons try desperately to keep moving.Another AnswerIn the case of incandescent lamps, the electricity does work on the filament, causing its internal energy to increase. This is accompanied by a rise in temperature which results in a loss of energy to the surroundings by (mainly) heat transfer and (to a lesser extent) electromagnetic energy in the form of visible light.
How did thomas Edison make light blubs?
Thomas Edison made light bulbs by developing a filament that could produce light when an electric current passed through it. He also created a vacuum inside the bulb to prevent the filament from burning out too quickly. Edison's improvements to the design of the light bulb made it more practical for everyday use.

You are using a bulb whose filament is broken will the bulb glow when connected to battery give reason?
No, the bulb will not glow when connected to a battery if the filament is broken. The filament is the part of the bulb that heats up and produces light when electricity passes through it. If the filament is broken, there is no path for the electricity to flow through and generate light.
Is resistance in the filament of a lamp essential or not?
Yes, the resistance of the filament of a light bulb is what generates enough heat to make the filament glow and produce light.
What year did Louis Lattimer make the filament for the light bulb?
2008
What type of filament will make the light bulb turn on for a longer period of time?
The filament is nothing to do with the light turning on, that is controlled by the switch.
Why is a copper wire not used to make filaments of electric bulbs?
Because the filament is in effect a resistor. Copper is too good a conductor to provide resistance to the current, and would simply allow the current to complete the circuit. The light is generated by the filament glowing as it heats up in resistance to the current. Tungsten is a much better resistor.

How does the inactivity of noble gases make them useful?
We use them as atmospheres when we don't want something to react, particularly with oxygen. For instance in a filament electric lamp, the tungsten filament gets extremely hot. If the bulb contained air, the filament would oxidise immediately, as it does if the glass develops a crack. That's why we fill them with argon.
What forms of energy does the electric light bulb made?
First let us understand the different parts that go to make up the light bulb shall we? The key component in a light bulb is the filament, this filament, ususually a thin piece of wire, is connected to two contact points. These points are then connected to the metal base of the bulb. When the bulb is attached to the light socket a circuit is then made. As the thin wire is part of the circuit it will have electicity passing through it when the power is switched on. The bulb glows because of the filament is thinner than that of the rest of the circuit. The filament gives off heat energy and begins to glow, this glowing we call light energy. You now have two forms of energy.
