Question

Which among tungsten and nichrome is a better conductor ?
(Resistivity of tungsten = 5.50 × 10–8 W–m and resistivity of nichrome = 110 × 10–8 W–m)

Answer 1

Answer:

Tungsten is a better conducter .

Explanation:

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.
