The invention of the light bulb affected how energy was used.
That varies, depending on the technology. In an incandescent light bulb, a wire is heated when electricity passes through it, until it glows. In a fluorescent light bulb, atoms in a gas get into an excited state, and emit light when the electrons fall back to their normal energy level.
A bulb does not light up if there is no voltage available across the bulb, or if the bulb is burned out.
No. The light bulb is two words, not a combination of light and bulb.
A light bulb that uses a filament is also known as an incandescent light bulb.
There are different era of technology of a light bulb.
The invention of the light bulb affected how energy was used.
electric light bulb
That can vary A LOT, depending on the specific technology used (the type of light bulb), and the brand.
led light i think is new update in bulb industry because the used less elctricity . it good for our environment.
The incandescant light is more of a heat bulb than a light bulb, being 200% less efficient (on average) in producing the same amount of light (measured in lumens) than a fluorescent bulb. That being said, the light bulb would be considered part of a luminaire.
the light bulb
Althought electricity was already discovered, the light bulb influenced greater technoglical improvement in electricity production and distribution. The advent of the light bulb also led to the development of just about every industry where light / illumination was required.
More watts means it uses more energy per second (watt is a unit of power). If it is a light-bulb of the same type of technology, the higher-watt light bulb would also give off more light.
In episode 2 mix void+glass=light bulb (new group... technology)
Some examples are Light bulb, fiber optics, laser surgury intruments.
Before the light bulb was invented, people used lanterns, candles, and fire for light. Today, with all the technology going on, we use electricity to produce light such as for the light bulb. So the most commonly used way to make light is by electricity.
