Electricity powered the light bulb in the 19th century. Thomas Edison is considered to be the inventor of the modern light bulb.
They are all powered by electricity.
Light in an optical microscope is either provided by light reflected off the mirror under the 'stage' - or by a battery/mains powered light bulb.
In an incandescent light bulb, the wire is heated until it glows.In a fluorescent light bulb, atoms are excited, which means the electrons are raised to higher enerty levels. When they fall back, they emit light.In an incandescent light bulb, the wire is heated until it glows.In a fluorescent light bulb, atoms are excited, which means the electrons are raised to higher enerty levels.

he woked on it for 15 years. He first made a airless glass that has the shape of a sphere and then he put in a filament (string that powers the light bulb) which was made out of carbon and powered the lightbulb through electricity
A bulb does not light up if there is no voltage available across the bulb, or if the bulb is burned out.
what is a conclusion for a battery powered light bulb
light r bulb same power taken

yes it can be powered by a potato:)
The battery chemically stores electricity so when you 'switch on' the light then electricity flows from the battery to the bulb. The bulb the heats up to glow white and the reflector shines the light out of the battery powered light
from a tap on a field coil

110 volts is what comes out of an average wall socket in America. A 100-watt bulb would be powered by 110 volts. You need to be more specific in your question to get a good answer. Small can't be measured.
