Answer» The melting point and of Tungsten is an alloy which has very high melting point and very high resistivity so does not burn easily at a high temperature. The melting point and of\xa0Tungsten\xa0is an alloy which has very high melting point and very high resistivity so does not burn easily at a high temperature. ... (e) Copper and aluminum are good conductors of\xa0electricity\xa0also they have low resistivity. So they are usually\xa0used\xa0for\xa0electricity\xa0transmission. |
