what are conductor and insulator? give one example of each
Answers
Answer:
In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them.Most atoms hold on to their electrons tightly and are insulators.
Their examples are as follows :
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.
Hope it helped you !
Pls mark it as brainliest and give a thanks !
Answer:
Materials that allow electric current to flow through them easily are called conductors. Example: Silver.
Materials that do not allow electric current to flow through them easily are called insulators.
Example: Plastic
