Different kinds of light use different mechanisms. Currently, the technologies used include incandescent lights, fluorescent lights, and LEDs.
In an incandescent light (that's the most wasteful light), a current heats up a wire, until it glows.
In a fluorescent light, the current excites atoms, i.e., it raises electrons to a higher energy level. When the electrons fall back, they emit light.
I believe LEDs work on a similar principle, i.e., exciting the atoms; however, the material is solid instead of a gas.

How does electrical discharge produce light?
By electricity
What causes electrical energy to be transformed into heat and light energy as a current flows in a light bulb?
Eletric current
What material stops the flow of electrical current?
Light energy
A from of energy that can produce heat and light magnestism and electrical charges?
Electricity
Can electrical currents in a circuit produce thermal energy light sound and magnetic forces?
Yes to all. -- Electrical current in a toaster produces thermal energy, often known as "heat". -- In a light bulb produces light. -- In the wires dangling from eaqr-buds produces sound. -- In a solenoid coil or motor stator produces magnetic forces.
What is bulb and its proccess?
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.
How does electrical discharge produce light?
By electricity
Is electrical current greater before or after light bulb?
Electrical current is equal throughout a series circuit.
What type of current does a storage battery porduce?
Electrical current
Does three motors make enough energy to run a light bulb?
Electrical motors use electrical energy, they don't produce it. Generators produce electricity. Also, since they come in very different sizes, you would have to take a look at the generator's electrical specifications, specifically its power (or multiply voltage x current), and compare to those of the light-bulb.
What does the light bulb do in a circuit?
Bulbs convert an electrical energy to produce light
What does the filament of a light bulb allows the light bulb to change electrical energy to?
The filament of a light bulb overs enough resistance to current flow, that the filament heats up so much that it will glow and produce visible light.
What causes electrical energy to be transformed into heat and light energy as a current flows in a light bulb?
Eletric current
What is the difference between heavy and light current in electrical engineering?
light current deals with control and telecommunication.while heavy current deal with machine which consume high current such as transformer ,generator ,electrical distribution above 415 volts
What does an electrical charges produce when it jumps from place to place?
an electrical charge produces a flash of light.
What are some ways to produce an electrical current?
Dynamo, alternator, solar panel.
What material stops the flow of electrical current?
Light energy
