What is the function filament?
filament is the source of light which gives to the plant to do a photosynthesis..
What form of energy is heat produced by filament?
Heat energy. When it is radiated off from the filament, it is mainly infrared light.
Where does the energy for a light bulb come from?
it come from the energy source in the middle of the light bulb he clearly asked what type of energy is it?!
What happens to the energy when you turn on an electric lamp?
Electricity flows through the filament, resistance in the filament causes heat and light energy to be created.
Why should the filament of bulbs be thermally isolated?
Energy, in the form of electricity, causes the filament to heat up and give off light. Any energy which the filament loses by heating the bulb does not create light, and so is wasted. Thermal isolation minimizes the heat loss of the filament, and therefore reduces wasted energy.
What is the main type of energy transformation that occurs in the filament of a light bulb?
Electrical energy (the electric current) is transformed into thermal energy (by heating the filament to incandescence), and this thermal energy creates electromagnetic energy in the form of light.
What is an example of a resistor that transforms electrical energy to light energy?
A lightbulb filament.
What energy transformation occurs when a battery powered flashlight is switched on?
Chemical energy is changed to electrical energy. Electrical energy heats the filament of the bulb, changing to heat. The hot filament glows, giving off light
What is filaments function?
filament is the source of light which gives to the plant to do a photosynthesis..
What is the thin wire in a bulb that changes electrical energy into light energy?
It is called the 'filament'.
What is the thin wire in a bulb that changes electrical energy into light energy called?
filament
Does energy change when it passes through a light bulb filament?
The energy won't change
