Question

why are filament of incandescent lamp made of thin tungsten wire?

Answer 1

$<b><i>$hey mate

here is your answer

______________________________

Tungsten has low Resistivity and as such only a thin wire film in bill high resistance necessary to produce in large amount of heat to light the world brilliantly brother tungsten has very high melting point 3300 Kelvin and as much the filament will not work at the high temperature 2400 Kelvin at which it becomes incandescent

so cause the filaments of incandescent lamps made of thin tungstan wire.

be brainly

Answer 2

Tungsten has a high resistance which is necessary to produce a large amount of heat to light the bulb.

Further, tungsten has very high melting point (3300K) and as such the filament will not burn at the high temperature (2400K) at which it becomes incandescent.
