Question: Who invented the first electric light bulb in 1879?
The first practical electric light bulb was invented by Thomas Edison in 1879. It was based on the principle of electric current being dissipated through a filament and generating heat and light. The original bulb was made from a carbon filament wrapped around a platinum element and a glass envelope filled with nitrogen. This filament was held in place by two insulated wires. When the electric current flowed through the filament, it generated enough heat and light to illuminate the room.
