Question

What is the difference between an electric insulator and an electric conductor? Give examples of materials that are electric insulators and examples that are electric conductors.

Answer 1

Solution: Electric conductors Electric insulators Conducting materials have free charges to move Insulating material doesn't have free charges to move. In conducting material current is allows to But in insulating materials current is not pass through them. So that conductors are allowed to pass through them. So that insulators good at conducting electricity Electrical conductors have zero resistance. Whle electrical insulator have high resistance. are poor at conducting electricity Metals are said to be conductors, because Most non metallic solid are said to insulators the outer most orbit of the electron is not because the outer most orbit of the electron is tightly bonded. Copper material is a good conductor tightly bonded. Glass material is good insulator. Examples, Examples Copper wires, steel frames, metal objects Rubber, mica, glass, quartz, plastics, and and salt solution. distilled water.
