Conductors, semiconductors, and insulators, the trio forms the most popular set of substances in electricity and its conductivity, and form one of the most exciting study materials in physics.<\/p>\n

The basic difference among them is that conductors, semiconductors, and insulators is their conductivity levels of electricity. Conductors have a high conductivity, which implies they enable energy to flow easily through them, such as electricity, heat, or sound. Semiconductors allow for moderate flow, whereas insulators have poor conductivity.<\/p>\n

As far as the basic difference is concerned, it is undoubtedly the levels or degree of conductivity of electricity. However, there are certain other differences with respect to their application, that clearly distinguish them from one another.<\/p>\n

In this article, let us focus on<\/p>\n

How does a conductor work<\/p>\n

How does a semiconductor work<\/p>\n

How does an insulator work<\/p>\n

Besides, we shall throw light on examples of conductor, semiconductors and insulators<\/p>\n

Band Theory<\/strong><\/h2>\n

One of the important ways in which the differences in conduction may be explained is Band theory. \u00a0Since this uses the material \u2018band\u2019 to explain a variety of physical properties of conduction, it is called band theory.<\/p>\n

In an individual atom, within the permissible energy levels, there are electrons that orbit its positive nucleus. Among the several atoms, the energy levels are reorganized in two bands, the valence band and the conduction band. The lower level of electrons is called the valence band while the conduction band refers to the higher level of electrons.<\/p>\n

There is an energy gap occurring between the bands in which there is no existence of electrons. As and when the conduction occurs, these electrons get into motion, and this can be possible only when there are spaces in the energy bands for them electrons to enter and move.<\/p>\n

What is a Conductor?<\/span><\/b><\/h2>\n

A conductor allows an electron to move easily from one atom to another when the right voltage is applied, as there are no band gaps between the valence and conduction bands.<\/p>\n

Some materials\u2019 conductor and valence bands overlap, allowing electrons to flow between the two overlapping bands. Because there is space for electrons to travel into the conduction band, one electron from the valence band moves into the other band, allowing conductivity.<\/p>\n

Can we name on most popular conductor of electricity? Among several, silver is most likely the finest electrical conductor we come up with in daily life. Other metals with good conductivity include gold, copper, steel, aluminum, and brass. These materials can be found in ordinary electrical equipment, either as cables or etched onto circuit boards.<\/p>\n

Although solids are often the best conductors, some liquids, notably liquid metals such as mercury, are equally effective at allowing energy to be transmitted through them.<\/p>\n

What are superconductors?<\/strong><\/p>\n

Superconductors are certain materials that will conduct without resistance at extremely low temperatures.<\/p>\n
