This is an electric lamp, or bulb. The electricity is used to excite electrons in a filament (incandescent), or a gas-filled tube (fluorescent), or in a diode (LED).
Liquid crystals (LCD) do not create light, but darken against a lighted background.
A device that converts light energy into electricity.
A solar cell or photovoltaic cell is a device that converts light directly into electricity by the photovoltaic effect.
A solar panel converts light into electricity.
A solar cell or photovoltaic cell is a device that converts light directly into electricity by the photovoltaic effect.
A solar cell is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect.
A light bulb is an output device because it produces light when electricity is applied to it. It takes the input of electrical energy and converts it into light energy.
A light bulb converts electricity into light. When electric current passes through the bulb's filament, it heats up and emits visible light.
Yes. A solar heater would do that, if there's sun light.
Wind turbine.
a device that converts electromechanical energy into electric energy.
Solar cell is the device which converts the light energy to electrical energy it convert photons to dc energy for more information you can visit the several sight which can give you information about solar cell. it is semiconductor device fabrication is done by using silicon p-n junction.
An incandescent lightbulb is an example of a device that converts electrical energy into light and heat. A loudspeaker is a device that converts electrical energy into sound.
