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 The bus conductor collected money from the passengers. 4. Metals, humans, earth, and animals are all conductors. But we can touch the electric wires with wood as wood is a poor conductor of electricity. The electrons move only if there is a difference called the potential difference along the conductor. A conductor is any piece of material that easily allows heat or electricity to pass through it. In a conductor electrons are flowing from B to A. These materials follow Ohm’s law as well as have a very small resistance. The difference of potential can be produced by a battery consisting of one or more cell. Conductor definition, a person who conducts; a leader, guide, director, or manager. What does CONDUCTOR mean? 5. The chapter lays emphasis on the understanding of electric current and its direction of flow in circuits. Define Thermal conductor.
