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.
Why is the filament inside an electric lamp made very fine?
The filament is fine so that its electrical resistance can be quite high. It is also long, for the same reason. Usually it is coiled up to fit the length in the lamp. The heating effect of electric current is proportional to the current squared, time the resistance (I*I*R). Most of the effect is due to the current. The current through the filament must be limited to stop it melting. Adding resistance will do that. Taking resistance away increases heating. So, a low energy lamp has a very thin filament and a high energy lamp will have a thicker filament.
How do electric rays generate electricity?
The wiring inside the light bulb is very thin (the filament) and glows when heated. The current through the thin wire heats up the filament wire so that it will glow. See the related link 'How Light Bulbs Work'.
How does the electric lamp function using electricity?
You plug it in and it lights up. Current flowing in the filament makes it white hot, and it emits light.
What actually gives off light in a light bulb?
Electric current through a filament (thin spiral) of tungsten causes it to heat up enough to glow brightly.
What is the hypothesis to how does a light bulb work?
When a current is passed through a thin wire filament it gets hot. Insulate the filament in a glass envelope with no air, and the filament glows brightly.
What is light produced?
A filament is heated by an electric current and photons are emitted.
What is light produced by?
A filament is heated by an electric current and photons are emitted.
What is the filament in lights?
Filament is a thin part of incandescent bulb which is the source of electric light that electric current passes through and heated it until it produce light.
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.
Construction and working of electric bulb?
initially when current pass through the filament
When electric current flows through the metal filament of light bulb electric energy is converted to?
Heat and light.
How does electric lamp glow?
The simplest electric lamp is the incandescent lamp. Electricity flows through wires to a tungsten or other metal with electrical resistance. Electrical resistance in the tungsten is increase by use of a long, very thin strand of metal called a filament. The electric current passing through the filament heats it up to a very high temperature (2000 to 5000 degrees) and at this high temperature it begins to glow brightly. The metal would actually burn up very quickly except that it is protected by the use of an inert gas inside the glass bulb.
Is the amount of current that flows in the wire of electric circuit the same as the current that flows in the filament of the light connected in that circuit?
yes
How can we increase the magnitude of the magnetic field of an electric magnet?
Increase the magnitude of the electric current.
Why does a light bulb filament get hot when electric current flows through it?
That is the result of resistance in the wire. In energy terms, some of the energy in the electric current is converted into heat.
