how to Use processes Tungsten in copper for fail filament
Answers
Answer:
Tungsten is used in an electrical bulb because it has a high melting point and does not oxidize. Thus, the filament of tungsten does not melt even though a large amount of heat is generated due to the passage of the current through the filament (through the heating effect of the current).
Explanation:
Answer:
In order to fail light filament, the chemical used on copper is tungsten. If the tungsten put in contact with copper, a chemical reaction is likely to cause copper filament to fail. This will the cause the torch not to function.
The melting point and resistivity of Tungsten are very high. At high temperatures, it does not burn quite well. Hence, tungsten is mainly used as the heating element of electric bulbs. Tungsten has a very high melting point and very high resistivity so does not burn easily at a high temperature.
