Main Question or Discussion Point

Hi ! Small doubts which need to be clarified.

1)What happens if tungsten is used in domestic wiring?

2)Fan has a regulator that is used to control and vary its rotational speed.
Would it be possible to minimize the consumption of electricity by setting
the regulator to the lowest speed?

Is the resistance of tungsten similar to copper ? If it is it would be about the same .
Light bulb filaments are made out of tungsten .

The resistance of a wire of tungsten would be more than three times the resistance of a similar size copper wire - so you'd need thicker cables.
Tungsten is much less common than copper and would cost a lot more for house wiring.
Taken together, those are good reasons for not using it!
The reason that lightbulb filaments are made of tungsten is that it has a very high melting point so they can be run at 'white heat' (3400ºC) and still survive. Copper melts at about 1080ºC so you could only have 'red hot' filaments.

If you run a fan slower, yes it will use less energy.

Also, tungsten does not bend very easily, it tends to break, so you could not go around corners very easily.

Tungsten is rarer, and harder to work with, which makes it much more expensive.
