1.	Why is tungsten metals selected for making the filaments of the bulbs
Answer» There are two reasons behind it\xa01.High melting point- it increases the life span of the bulb2.High resistivity- due to it enough energy produces & bulb able to emit light.\xa0<br>Because it have very high melting point about 3380 degree celceius.
