Question

Explain how Thomas Alva Edison invented a bulb.​

Answer 1

Answer:

By January 1879, at his laboratory in Menlo Park, New Jersey, Edison had built his first high resistance, incandescent electric light. It worked by passing electricity through a thin platinum filament in the glass vacuum bulb, which delayed the filament from melting. Still, the lamp only burned for a few short hours

• 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.
• His invention was known as the Electric Arc lamp.
