What did Joseph Swan use to improve the light bulb?
Like other early inventors, Swan used a carbon rod with low electrical resistance in his lamp. Due to the relationship between resistance and current, a low resistance element required lots of current in order to become hot and glow.
Was Tesla the real inventor of the light bulb?
Contrary to popular belief, the light bulb wasn’t actually Edison’s invention. They worked together for a short time, Tesla helping Edison to improve his inventions, but ultimately they ceased working together.
How long did Swan’s light bulb last?
about 13½ hours
Swan’s electric lamp deposited a dark layer of soot inside its inner surface, obscuring the light. Swan experimented with a filament of carbonized paper, but it burned out quickly. The bulb lasted just about 13½ hours. Still, that was long enough to signal that there could be a real future for this invention.
