A light bulb does not generate energy, it converts energy from one form to another. Specifically it converts electrical energy to heat and light (electromagnetic energy) and some magnetic energy.
It uses the remaining 15% to generate light and thus it is 15% effective.
If you're using it to generate light, 10 percent efficient. If you're using it to generate heat, 90 percent efficient.
Mechanic energy is converted in to light bulb , in bulb the electric energy converted into heat and light
In a light bulb, electrical energy is transformed into light energy and heat energy.
Energy does not happen. Electrical energy is routed through a light bulb, and some of it is converted to heat energy and light energy inside the bulb.
A light bulb turns electrical energy into light and heat energy.
Electricity is the source of energy in a light bulb.
A light bulb uses electrical energy, and produces light, as well as heat.
Most of the energy in a light bulb is heat energy.
It will be like a generator and generate it to light up the light bulb. I hope this helped you and good luck with your answer!
light and heat energy occur in a light bulb when it is turned on.
A light bulb is not an example of electromagnetic energy, but the light which the bulb gives off is an example of electromagnetic energy.
When lighting a light bulb, it is changed into light and heat/thermal energy.
It varies, depending on the specific model, but an energy-saving (fluorescent) light bulb should save at least half the energy, for the same luminosity, compared to the old-fashioned incandescent light bulbs. The incandescent light bulbs ought to be outlawed, except for specific purposes where the heat they generate is actually needed.
Yes it is. Electrical energy going into the bulb is converted into light and heat energy.
the energy that produces heat in a light bulb is electromagnetic.
A light bulb IS not a form of energy, it CONVERTS energy. A lightbulb converts electricity into heat and visible light.
Light energy leaves when light bulb is off. No electrical energy is supplied.
it come from the energy source in the middle of the light bulb he clearly asked what type of energy is it?!
Light has heat and light energy. Example is bulb.
To plug it in, you use your muscle energy. When current flows through the bulb,electrical energy converted to the heat and light energy in the bulb.
An incandescent light bulb does that, as does a radiant heating element. A light-emitting diode (LED) also generates light from electricity from the excitation of a semiconductor junction. A fluorescent bulb can be used to create light from electricity by stimulating the chemical to fluoresce. Gaseous bulbs can generate light from electricity, such as a neon/argon/halogen bulb with a high-voltage applied to the gas inside.
An energy efficient light bulb will use less energy than a normla light bulb; this means it produces less heat (heat is usually an unwanted byproduct of producing light).
