The higher the temperature of the filament, the brighter the light emitted
When the filament is in an incandescent state, it is like a red iron that glows and emits light
Spiral filament constantly heat accumulation, making the filament temperature of 2000 degrees Celsius or more
Its working principle is: current through the filament (tungsten wire, melting point of more than 3000 degrees Celsius) to produce heat
An incandescent lamp is a device that converts electrical energy into light energy to provide lighting
