if only a small percentage of the electrical energy fed into a common lightbulb is transformed inot light .?

Question

What happens to the remaning energy?

Answer 1

Incandescent Light bulbs work on the principle of running an electric current through a filament. In the process, power is dissipated in the filament and its temperature rises. As its temperature rises it begins to glow. The higher the filament's temperature, the more energy it puts off in the form of visible light (at low temperatures will only 'glows' in the IR end of the spectrum but then increases into higher frequencies at higher temperatures).
So the light bulb works by turning electrical energy into heat, which then gets radiated off as light. But only a small fraction of the energy dissipated in the light bulb actually gets transformed into visible light, most of it just stays as heat or is only emitted as Infrared radiation...which we cannot see and might as well be heat.

Answer 2

Almost all of the energy gets transformed into heat. Current I running through a resistance R generates total power P = I^2 * R.

Answer 3

yes it will emitt light but not visible light as part of the spectrum which is visible has comparatively high frequency which can be emitted by very hot object. now if less current is passed through a bulb the it will not heat up very very much & will not emit light

Answer 4

share is particularly asking the question "how lots out of one hundred?"on your occasion ,whether that is 40-one out of three hundred then say that is X of one hundred.placed it interior the equation 40-one/3 hundred=X/one hundred 41x100=X x 3 hundred X=40-one/3 hundred x one hundred=13.7 approx hassle-free thank you to look at is,divide the 40-one via 3 hundred and then multiply via one hundred.

Answer 5

It turns into heat.
Light bulbs get extremely hot!!!
