What Are Conductors? In simple terms, an electrical conductor is defined as materials that allow electricity to flow through them easily. This property of conductors that allow them to conduct electricity is known as conductivity. The flow of electrons in a conductor is known as the electric current. The force required to make that current flow through the conductor is known as voltage. When a charge is transferred to such an element, it gets distributed across the entire surface of the ...

Master Physics concepts with Vedantu-learn and boost your grades! insulator , any of various substances that block or retard the flow of electrical or thermal currents. Although an electrical insulator is ordinarily thought of as a nonconducting material, it is in fact better described as a poor conductor or a substance of high resistance to the flow of electric current. Different insulating and conducting materials are compared with each other in this regard by means of a material constant known as resistivity. See also semiconductor. Electrical insulators ... Insulators: Types, Properties, Material, Causes of Failure and Applications The insulators or line insulators are used in overhead transmission and distribution lines. The overhead conductors are supported on the poles or towers. In order to avoid the flow of current through supporting poles, the insulators are used to support the line conductors. Hence, the line insulators are used to provide insulation to the power conductor from the ground. In a high-voltage transmission line, the ...
