It depends on the type of bulb.
The function of a light bulb in an electric circuit is that it turns electrical energy into light.
A light bulb is an electric light that uses the process of a filament wire that is heated to produce an electrical current. When the electrical current passing throught the light bulb it produces light.
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light which produces light with a wire filament heated to a high temperature by an electric current passing through it, until it glows.
Heat, which then produces light.
The electric light bulb came first but was patented later that the telephone was.
The bulb produces the light.
Electrical energy absorbed by the lamp's filament produces thermal energy as well as light.
a bulb is light bulb
Because the filament will burn, and the filament is the part that produces the light.
filament
Incandescent
The answer should be pretty obvious. Just try to think about this. What energy is used? What does the light-bulb produce? In this case, the light-bulb requires electricity, and it produces both heat and light, so electrical energy is converted into light energy and heat energy.
