Why is tungsten used almost for all filaments of electric lamps?
Verified Answer
Why is tungsten used almost for all filaments of electric lamps?
Because tungsten is a free element, that has the highest melting ponit (3422 degree c) of all non-alloyed metals, but low resistivity (5.60 e-8 ohm.m) and hence, when electricity passes through it, it becomes white-hot and starts glowing. Thus, it is used to make incandescent bulb filaments.
