When electrical current flows through a lightbulb (whether it's CCFL, halogen, or incandescent), the trade-off is light and heat energy.
In a traditional light bulb, the electrical energy is converted to heat. The filament gets hot and emits the thermal energy as light. The electrical energy itself is not directly converted to light but goes through the thermal energy stage.There are many kinds of lights and more complicated processes which are not described in this brief answer.
Electrical resistance is technically not the same as friction though one could be used as a model for the other. Electrical resistance in a light bulb can be seen by the light that is emitted due to the heating of the filament when current is passed through it (electrical potential is transformed into heat).
In typical light bulbs, or incandescent bulbs, the resistance to the current directed through the filament causes the filament to heat up, thus radiating light. The glass bulb around the filament is vacuum sealed to remove oxygen, which would rapidly oxidize and destroy the super heated, ultra thin filament. there are variations of this technology in which the bulb is not a vacuum, but is instead filled with different gasses surrounding the filament, which allows the filament to burn even hotter, creating more light. fluorescent bulbs work by creating a reaction between mercury vapor and phosphors. electric current excites the mercury atoms, which then release ultraviolet light. The ultraviolet light causes the phosphors to fluoresce, which creates light in our visible spectrum.
A light bulb works by passing an electric current through the filament, which is usually made from a high resistance substance such as tungsten. When the current flows through, the filament glows which produces the light. When it burns out, no electricity passes and no glowing occurs. Source: i just know
Electrical energy is converted into light and heat when electric current flows through the metal filament of a light bulb.
The electrical energy is converted to both heat and light energy.
Heat, which then produces light.
The electrical current comes into the bulb from the metal side,flow through the filament ,and out the tip.
Heat and light.
it stays there. the electricity travels back and forth through the filament until you turn the lighbulb off.

That is the result of resistance in the wire. In energy terms, some of the energy in the electric current is converted into heat.
When the flashlight is ON , electrical current is flowing from one terminal of thebattery, through the light-bulb filament, to the other terminal of the battery.
With copper wire.----------------------------------------------------------------------------------------------------Improved Answer By: AP_METThe voltage x amps current of the battery discharges electrical wattage power in the form of electons passing through a tungsten filament.This tungsten filament is built within a glass bulb which has had all air (78% nitrogen & 21 % oxygen) evacuated from it and filled with an inert nobel gas.The tungsten filament will become extremely hot as electrical wattage passes through it and will glow nearly white-hot within the non-air gas inside of the glass bulb.The energy transfer from the battery to the light bulb's filament is as follows:Chemical energy from the battery converted into electrical energy passed through the tungsten filament converted into heat energy then into light energy.--------------------------------End Improved Wiki Answer ---------------------------------

Fuel helps but electrical energy is converted to mechanical energy through a motor, a machine with magnets that converts the electrical current into mutually repelling magnets causing mechanical motion.
