who invented the electrical light bulb?

Question

and when was it invented?

Answer 1

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.

In 1877, the American Charles Francis Brush manufactured some carbon arcs to light a public square in Cleveland, Ohio, USA. These arcs were used on a few streets, in a few large office buildings, and even some stores. Electric lights were only used by a few people.

The inventor Thomas Alva Edison (in the USA) experimented with thousands of different filaments to find just the right materials to glow well and be long-lasting. In 1879, Edison discovered that a carbon filament in an oxygen-free bulb glowed but did not burn up for 40 hours. Edison eventually produced a bulb that could glow for over 1500 hours.

Answer 8

In 1847, An impoverished horticulturist from Holland, hoping to electrically stimulate his tulip bulbs into sprouting early by attaching electrodes into it got an unexpected result as the tulip bulb glowed incandescently as the current coursed though it. But alas, his fame went unnoticed for his bulbs proved to be a fire hazard.
