The first electric light was made in 1800 by Humphry Davy, an English scientist. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. This is called an electric arc.
Much later, in 1860, the English physicist Sir Joseph Wilson Swan (1828-1914) was determined to devise a practical, long-lasting electric light. He found that a carbon paper filament worked well, but burned up quickly. In 1878, he demonstrated his new electric lamps in Newcastle, England.

What is a filament that glows white hot in electric light bulbs?
Tungsten is the filament used in electric light bulbs that glows white hot when subjected to an electric current.
Why bulbs light?
Bulbs light up when an electric current passes through the filament, which heats up and emits light. This process is called incandescence.
How many light bulbs were in use at 1902?
It is difficult to determine the exact number of light bulbs in use in 1902 as there is no comprehensive record. However, it is estimated that the number of electric light bulbs in use around the world at that time was in the millions, as electric lighting was becoming more popular.
Who invented the long lasting filament electric light bulb?
Thomas Edison is credited with inventing the long-lasting filament electric light bulb in 1879. He developed a carbonized bamboo filament that could last for up to 1200 hours, making light bulbs practical for everyday use.
How electric bulbs works?
Electric bulbs work by passing an electric current through a filament, which heats up and produces light. The filament is typically made of tungsten, which has a high melting point. The light produced is a result of the filament glowing as it reaches high temperatures.
Where did thomas edison invented light bulbs?

Were there light bulbs in the Victorian era?
Yes; Edison invented the light bulb in 1879, though electric light bulbs weren't the dominant source of light until after World War I. Most Victorian homes used gas lighting or candles.
What is a filament that glows white hot in electric light bulbs?
Tungsten is the filament used in electric light bulbs that glows white hot when subjected to an electric current.
Who invented the first practical incandescent electric light bulb?
Successful electric light bulbs were invented almost simultaneously by Alfred Swan in Britain, and Thomas Elva Edison in USA. Thus in UK they were marketed as Ediswan products. [After the lawyers had benefited from protracted battles.]
