Question

who invented electric blub​

Answer 1

Answer:

The invention of the lightbulb (specifically the incandescent bulb) is a rather contentious issue, to say the least. Whilst Thomas Alva Edison often gets all the credit, is this actually true?

Like many inventions throughout history, the modern lightbulb is actually a combination of many tiny steps. Many historians claim that no less than 20 inventors had produced various designs of incandescent lightbulb long before Edison.
