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.
How energy is transformed light from flashlight?
Battery electric energy is converted to light energy of flashlight.
What is the energy transfer in an electric cooker?
in the cooker energy transfers that goes in is electric energy, transfers that go out are heat and light energy
What is an electric component that transforms electric energy into heat and light?
That is a light bulb, or any filament such as the one in a radiant electric fire.
What types of energy does a light bulb use?
electric energy
What was the purpose of the electric light bulb?
To convert electric energy into light energy
What energy changes are involved when an electric light shines?
electric energy changes to light & heat energy when light shines.

Breif answer on what is electric energy?
Electric Energy is the energy of the Universe. All energy is electric energy. Gravitational Energy is electric in the sense that matter is held together by electric energy. Briefly, Electric energy is E= - q1q2 zc/r where q is the electric charge, z is the free space resistance and c is the speed of light.
