Question

How does an electric bulb produce light? ​

Answer 1

• An electric current is gone through a skinny metal filament, heating the filament till it glows and produces light-weight.
• After the electricity has created its means through the metal filament, it goes down another wire and out of the bulb via the metal portion at the facet of the socket.
• The 3 main classes of electrical lights square measure incandescent lamps, that manufacture light-weight by a filament heated white-hot by the electrical phenomenon.
• Tungsten is a smaller amount economical whereas CFL has a lot of economical glass bulbs. luminousness is measured in lumens per watt.
• LEDs square measure the foremost economical, manufacturing fourfold a lot of luminousness than metal.

Answer 2

• As we know that the electric bulb converts electrical energy to light.

• The bulb produces light when electric current flows through it.

• As we know by sending the electric current through the filament.

• The light bulb turns electricity into light.

• Filament resistance heats the bulb, it is made up of tungsten metal.

• Light can be produced when the filament gets hot.
