Light contains energy. You may think of it as the kinetic energy of the photons which,
according to quantum theory, are the quanta of the electromagnetic field. You may also
think of it as the energy contained in the electric and magnetic fields which make up the
light wave. This duality is a basic part of quantum theory. Which picture is the most
convenient (both are correct) depends on the experiment used to detect the energy.
If you use the photoelectric effect where the light photons bang into electrons, giving them
kinetic energy and knocking some out of the material, the photon picture is most appropriate.
If you let the light hit your skin, hoping to get a tan, or focus sunlight on a pot of water
to heat it up, the wave picture is more convenient. Then the electric field exerts an
electric force on the electrons, causing them to accelerate and gain kinetic energy. The
electric field is oscillating, reversing sign about 10^15 times per second (that is 1
followed by 15 zeros). So the electron is pushed back and forth, colliding with other
electrons and atoms in the material, heating
them up.

What are the five devices that use electrical energy. write the forms of energy into which electrical energy is converted by each device.?
Light bulb: Electrical energy is converted into light and heat energy. Electric heater: Electrical energy is converted into heat energy. Television: Electrical energy is converted into light and sound energy. Electric fan: Electrical energy is converted into mechanical and sound energy. Computer: Electrical energy is converted into heat and sound energy, as well as processing and display energy.
When electric currents flow through the metal filament of a light bulb electric energy is converted to?
When electric currents flow through the metal filament of a light bulb, electric energy is converted to light and heat energy. The filament heats up due to the resistance in the metal, eventually producing light as it emits photons.
Is electric energy converted to heat energy or light energy?
Yes, electrical energy can be changed into thermal (heat) energy. Light is electromagnetic energy, and electricity can be changed into light energy. We know that a resistance heater changes electrical energy into thermal energy. An electric range does this, as does an electric space heater. We see electrical energy changed into light in fluorescent lights.
What electrical energy is converted to another form of energy?
The electrical energy supplied to an electric motor
What type of energy is converted in an incandescent lamp?
Electric energy is converted into light and heat energy in an incandescent lamp. The electric current passing through the filament of the lamp heats it up, causing it to emit light as well as heat.
How can electric energy can be converted to another form of energy in your home?
yes... for example electrical energy is converted to heat and light energy in a light bulb
When electric flows through the mental filament of a light bulbelectrical energy is converted to?
The electrical energy is converted to both heat and light energy.
What energy changes are involved when an electric light shines?
When an electric light shines, electrical energy is converted into light energy and heat energy. The electrical energy is converted into light energy, which is the main purpose of the light bulb, while some of the energy is also released as heat energy due to the resistance in the light bulb filament.

Can electricity be converted into Energy?
Electric energy can be converted into many things, all of them are other forms of energy. Electric energy can be converted into heat energy, like in many stoves and ovens. Electric energy can be converted into sound energy, which happens in speakers. Electric energy can be converted into mechanical energy, like with electric motors in fans and other devices. Electric energy can be converted into light energy as with a light bulb. Unfortunately, we do not currently have the technology to turn energy forms into matter as is shown in many sci-fi shows like Star Trek's replicators. Every energy is able to change its type. For example sound energy can be converted into electrical , light, heat and in many other forms.
When electric energy flows through the metal filament of a light bulb energy is converted to?
Heat, which then produces light.
What type of energy is converted in an incandescent lamp?
Electric energy is converted into light and heat energy in an incandescent lamp. The electric current passing through the filament of the lamp heats it up, causing it to emit light as well as heat.
