Answer:
The typical incandescent light bulb contains a thin wire (usually tungsten) called a filament that has a high electrical resistance. This filament gets very hot when an electric current passes through it. The intense temperature makes the filament glow brightly.

Answer:
The filament of an electric bulb glows because of the heating effect of electric current.As the current passes through the bulb it heats the filament which gives off light...the filament then heats off and becomes red hot as a result of this it begins to glow,turning electrical energy to light energy.
