Detailed explanation-1: -Hence, Tungsten is used in bulbs due to its high melting point and resistivity.
Detailed explanation-2: -Incandescent bulbs typically use a tungsten filament because of tungsten’s high melting point. A tungsten filament inside a light bulb can reach temperatures as high as 4, 500 degrees Fahrenheit. A glass enclosure, the glass “bulb”, prevents oxygen in the air from reaching the hot filament.
