Discussion Overview

The discussion centers on the implications of using tungsten in domestic wiring, including its electrical properties, cost, and practical considerations. It also touches on the efficiency of fan speed regulation in relation to electricity consumption.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • Some participants question the resistance of tungsten compared to copper, with one suggesting that tungsten's resistance would be more than three times that of copper, necessitating thicker cables.
  • It is noted that tungsten is much less common and significantly more expensive than copper, which raises concerns about its practicality for house wiring.
  • One participant highlights that tungsten's high melting point allows it to be used in light bulb filaments, enabling them to operate at higher temperatures than copper could withstand.
  • Another participant confirms that running a fan at a lower speed would indeed reduce energy consumption.
  • Concerns are raised about tungsten's brittleness, suggesting that it would not be suitable for wiring that needs to navigate corners easily.
  • Participants mention the difficulty of working with tungsten due to its rarity and physical properties, which adds to its cost-effectiveness issues.

Areas of Agreement / Disagreement

Participants express multiple competing views regarding the feasibility and practicality of using tungsten in domestic wiring, with no consensus reached on its overall suitability.

Contextual Notes

Limitations include assumptions about the electrical properties of tungsten versus copper, the economic implications of material choice, and the physical handling characteristics of tungsten in wiring applications.

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.
