Question

why tungsten is chosen as lighting element in bulb in terms of its resistivity
​

Answer 1

Answer:

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.

Answer 2

Explanation:

1) Thungsten has a very high melting point and hence doesn't melt even if high amounts of current is passed

2) It doesn't oxidised at very high temperatures

3) It starts glowing at high temperatures and that is what we need in a little light bulb
