Question

Who invented the light bulb and what was the reason behind it?

Answer 1

Thomas Edison
the reason behind is  thin filament with high electrical resistance would make a lamp practical because it would require only a little current to make it glow. He demonstrated his light bulb in December 1879. Swan incorporated the improvement into his light bulbs and founded an electrical lighting company in England.
