Write a note on how tungsten and Nichrome is used?
Answers
Answer:
The reason tungsten is used is because it has the highest melting temperature of any element at 3600K, where as nichrome melts at 1600 K which is almost to cold to give off light (maybe dark red). To generate a lot of heat you need a big resistance

To generate a lot of heat you need a big resistance.Tungsten is used for making filament of an electric bulb due to the following reasons: Being an alloy it has a very high melting point. It has very high resistivity so it does not burn easily at room temperature. The lamp glows at high temperatures.
