- The filament is attached to metal contacts that are hooked to a power supply so electricity can flow through it. When the electric current flows through the filament, the atoms are agitated and the electrons within them are excited to higher energy levels as soon as they absorb energy from the flowing current.

Before the invention of the light bulb, illuminating the world after the sun went down was a messy, arduous, hazardous task. It took a bunch of candles or torches to fully light up a good-sized room, and oil lamps, while fairly effective, tended to leave a residue of soot on anything in their general vicinity.
When the science of electricity really got going in the mid 1800s, inventors everywhere were clamoring to devise a practical, affordable electrical home lighting device. Englishman Sir Joseph Swan and American Thomas Edison both got it right around the same time (in 1878 and 1879, respectively), and within 25 years, millions of people around the wo...
Light is a form of energy that can be released by an atom. It is made up of many small particle-like packets that have energy and momentum but no mass. These particles, called light photons, are the most basic units of light. (For more information, see How Light Works.)
Atoms release light photons when their electrons become excited. If you've read How Atoms Work, then you know that electrons are the negatively charged particles that move around an atom's nucleus (which has a net positive charge). An atom's electrons have different levels of energy, depending on several factors, including their speed and distance ...
The wavelength of the emitted light (which determines its color) depends on how much energy is released, which depends on the particular position of the electron. Consequently, different sorts of atoms will release different sorts of light photons. In other words, the color of the light is determined by what kind of atom is excited.
This is the basic mechanism at work in nearly all light sources. The main difference between these sources is the process of exciting the atoms.
Aug 26, 2014 · When a light bulb connects to an electrical power supply, an electrical current flows from one metal contact to the other. As the current travels through the wires and the filament, the filament heats up to the point where it begins to emit photons, which are small packets of visible light .
May 21, 2015 · The operating principle behind the light bulb is very simple: you run an electric current through a thin filament, which causes it to get hot. Hot objects emit light, so the bulb...

Oct 2, 2005 · Question. How does a light bulb work? Answer. A light bulb is an electrical filament. What you have is a long piece of wire, and when you connect this to a socket, it basically completes a circuit. As electricity passes through, the electrical current excites the metal and gets it hot.
