explain conductors and insualtors with examples?
Answers
materials that are good in transferring heat to cool bodies through conduction for example all metals are good conductors of insulators are materials
Answer:
Examples of conductors include metals, aqueous solutions of salts (i.e., ionic compounds dissolved in water), graphite, and the human body. Examples of insulators include plastics, Styrofoam, paper, rubber, glass and dry air.
(a) Conductors: The substance in which the electric current flows from one place to another place easily are called conducting materials. For example, Silver, Copper, Aluminium, Iron, Mercury, Salt solution, Acid, Base, Human body and Earth, etc. are good conductors of electricity. silver is the best conductor. When the charge is given to the conductor, it gets disturbed readily over the entire surface of the conductor and no charge is found inside the conductor.
(b) Insulators : Insulators are the materials or substances which resist or don’t allow the current to flow through them. In general, they are solid in nature.Wood, cloth, glass, mica, and quartz are some good examples of insulators. Also, insulators are protectors. They give protection against heat, sound and of course passage of electricity. Furthermore, insulators don’t have any free electrons. It is the main reason why they don’t conduct electricity.
