Discussion Overview

The discussion centers around the relationship between conductors and inductors, exploring whether all conductors can function as inductors and vice versa. Participants delve into the definitions and properties of conductors, inductors, and insulators, examining concepts of charge and inductance.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • One participant questions if all conductors can be inductors and if inductors can be considered conductors, expressing confusion about the relationship between charge and inductance.
  • Another participant asserts that conductors and insulators are distinctly defined materials, with conductors allowing free movement of electrons and insulators presenting significant barriers.
  • It is claimed by some that all conductors possess inductance without exception.
  • A later reply clarifies that the initial confusion may stem from misinterpreting "inductor" when discussing conductors and insulators, suggesting that the focus should be on the properties of these materials rather than inductance.
  • One participant proposes that all real wires that conduct electric current can be considered inductors, questioning what might be missing from this assertion.
  • Another participant emphasizes that conductors do not switch to become inductors; rather, inductance is an inherent property of conductors, particularly when shaped in specific ways, such as in coils.
  • There is a correction regarding the terminology, clarifying that "inductor" is often confused with "insulator," and that materials do not typically switch between being conductors and insulators.

Areas of Agreement / Disagreement

Participants express differing views on the definitions and relationships between conductors, inductors, and insulators. There is no consensus on whether all conductors can be classified as inductors, and confusion persists regarding the terminology used in the discussion.

Contextual Notes

Some participants highlight the importance of precise definitions and the potential for misunderstanding due to the use of terms like "inductor" and "insulator." The discussion reflects a range of interpretations regarding the properties of materials and their behavior under different conditions.

Can all conductors be inductors and could all inductors be conductors?

I get confused about this because I know that inductor can be positively charges by a conductor. Can an conductor become an inductor by losing its charge from an inductor?
 
Physics news on Phys.org
I would say, outside of an external means (say temperature) to change the chemistry or physical properties of a material, that a conductor cannot be an insulator and vice-versa. The two materials are exclusively defined. A conductor is a material where the electrons have no barriers from moving from the valence band to the conduction band and are more or less free to move about the material. An insulator is a material that has a significant barrier between the energies of the valence electrons and those of the closest conduction band levels. A semiconductor has properties of both in that there is still a bandgap (a series of energy levels between the valence and conduction bands that electrons cannot exist at), but the bandgap is small enough that we can excite electrons from the valence to the conduction band by injecting sufficient energy into them.

I don't think he means inductance and capacitance, but insulator and conductor in terms of the chemical (and atomic) properties of the material.

Ok, how about: All real wires irrespective of their their chemical and atomic properties as long as they conduct electric current are inductors.

What am I missing?

$#&!%@. I think he means INSULATOR and conductor, I got caught up with the word "inductor" that he was using. Going off his positive and negative charges statements, I assumed that he was talking about conductors and insulators where you can strip off the electrons of an insulator to make it positively charged and negatively charge a conductor. Don't know why I kept using his word "inductor." Otherwise his statement about charges does not make sense in terms of inductance and conductance. I'll change my previous posts to reflect this.
 
So from what I understand is that conductors and inductors are constantly
switching. Is this correct?

No mapa. You mean insulator not inductor. Inductor means something completely different.

And no they aren't usually changing.

Every conductor has inductance. It doesn't switch from being a conductor and being an inductor, inductance just comes with conducting current. An inductor is just a conductor shaped to exaggerate the inductance...a wire wound in a coil. Inductors are not charged, either positively or negatively.

If you mean insulator instead of inductor, then in a substance is either a conductor or an insulator, materials generally don't switch between the two. If enough voltage is applied, an insulator will conduct current, but this generally destroys the insulator.

Charge isn't involved here the way you were describing either...insulators and conductors are both normally electrically neutral, but can be positively or negatively charged. Charge doesn't make something an insulator or a conductor. (or an inductor)
