Question

Why the tungsten is used almost exclusively for filament of an electric lamp?

Answer 1

Answer:

tungsten has high melting point .it does not melt at high temperature .it retains as much of heat generated ,so that it become very hot and emits light .that is the reason why tungsten is used as filament of electric lamps .

Answer 2

Answer:  It is because,                                                                      1)Tungsten has high melting point above 3380 degree                2)It has low resistivity                                                                        3)Do not oxidise readily at high temperature                                      4)It can be drawn in to very thin wires                                                                                  pls mark brainlist ans
