Question

Is there any difference between bad conductors and insulators.Explain with an example

Answer 1

Bad conductorsare those which can conduct electricity but offers more opposition (resistance) to the flow of current compared to the flow of current in a good conductor. Example: Drinking water is a bad conductor of electricity; Silver is a very good conductor of electricity. Iron is a bad conductor of electricity compared to copper. In bad conductors the strength of the current is reduced. Insulatorsare those substances that don’t conduct electricity at all. Example: Kerosene is an insulator. Current through an insulator is always zero.
