Am I a Dominant or Submissive Personality Quiz
According to physics, conductors are materials that allow the flow of charge in one or more directions. Conductors allow charge transfer through the free movement of electrons. Unlike conductors, insulators are materials that impede the free flow of electrons from atom to atom and molecule to molecule. The resistance of a given conductor depends on the material from which it is made. Insulators are materials that impede the free flow of electrons from one particle of an element to another. If we move some amount of such element at any point, the charge remains at the initial location and is not distributed on the surface. The normal process of charging such elements involves charging by rubbing, electrons do not move freely within the insulator. So let's start this quiz and know about the Conductor And Insulators.
