How does a light bulb work?

How does it work?
Electricity flows through a thin wire in the lightbulb called the filament. The filament used in a bulb has a property called "Resistance", resistance is the amount of friction that an object will put against electricity. A filament has a lot of resistance electricity. Therefore as a result of this, the filament heats up and starts glowing. The filament converts electrical energy to light energy.
