Electricity..,  the most common word that we hear in our day-to-day life. Though it is not visible to us, we feel incomplete in the absence of it. Our lives would be impossible to imagine without electricity. That is the impact it has on our lifestyle. Even our environment is related to electricity in the form of lightning and thundering. Regardless of its physical existence, there exists a principle in science behind it. Electricity is a physical phenomenon that is associated with the matter and motion of charges present in it. Electricity and magnetism are relative phenomena of electromagnetism. Electricity is dependent on the presence of an electric charge (positive or negative) in matter, which produces an electric field. So, as electricity is defined as the motion of an electric charge in a particular direction, it causes an electric current and it produces a magnetic field. Notably, only negative charges (referred to as electrons) are responsible for the generation of elect...

The term "conductor" has many different meanings in different contexts, but in electrical terminology, it refers to a material that allows electricity to pass through it. Those materials are usually metals, which have free electrons in them that come into motion when an external force (electromotive force) is applied between their terminals. The tendency to pass electricity through it is known as conductivity. This conductivity depends upon the resistance offered by the material. And based on their conductivity, the electrical conducting materials have been classified into conductors, semiconductors, and insulators. Recalling a few chemistry concepts, "an atom" is the basic constituent of all matter (whether elements or compounds), according to the modern atomic model theory. According to Rutherford's atomic model, an atom consists of a nucleus in the centre surrounded by orbiting electrons (negatively charged), as seen in the below figure. The electrons have ...
