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.
Thomas Edison is credited with inventing the first practical incandescent light bulb filament in 1879. He used a carbonized bamboo filament that gave the bulb a longer-lasting and brighter light compared to previous designs.
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.
Thomas Edison encountered the challenge of finding a long-lasting, practical filament material that could sustain a stable light output without burning out quickly. He experimented with various materials before discovering that a carbonized bamboo filament worked effectively.
Tungsten is the filament used in electric light bulbs that glows white hot when subjected to an electric current.
Thomas Edison is credited with inventing the incandescent light bulb in 1879. He developed a practical and commercially viable light bulb by creating a long-lasting carbon filament inside a vacuum-sealed glass bulb that could produce light when an electric current passed through it. Edison's invention revolutionized the way we illuminate our homes and businesses.

When electric currents flow through the metal filament of a light bulb, electric energy is converted to light and heat energy. The filament heats up due to the resistance in the metal, eventually producing light as it emits photons.
Filament is a thin part of incandescent bulb which is the source of electric light that electric current passes through and heated it until it produce light.
The electric current passing through the filament in an incandescent light bulb heats it up. This causes the filament to glow and produce visible light.
Thomas Edison is credited with inventing the carbon filament used in the first practical incandescent light bulb. He experimented with various materials before finding that carbonized bamboo was the most effective in producing a long-lasting light.
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.
