Question

how does an electric bulb work?​

Answer 1

An electric bulb is one of the revolutionary inventions ever made in the history of mankind. The working of an electric bulb is quite simple. When electric current flows through the filament made up of tungsten, it heats up emitting visible light.

Answer 2

【H】【e】【y】【a】

➡️The working of an electric bulb is quite simple. When electric current flows through the filament made up of tungsten, it heats up emitting visible light.

A filament has a lot of resistance to electricity.

Therefore as a result of this, the filament heats up and starts glowing, converting electrical energy to light energy.

This is because of the Joule-effect, which means that resistances heat up when electrical current runs through them.
