Good conductors are those which can conduct electricity easily and bad conductors are those which cannot conduct electricity (or can conduct poorly, because of very high resistance).
Good conductors: (All metals except tungsten and non metal graphite)...copper, aluminium, silver....graphite
Bad conductors: Glass, plastic, rubber, wood, nichrome.
Nichrome is a material which has a very high resistance....this means that it can conduct electricity but very, very poorly.......it gets heated up quickly and hence used in heaters, geysers, etc.

1. Good conductors - Aluminium , silver etc....
2. Bad conductors - Plastic , rubber etc....
3. Due to the nature of passing current through metals ( copper , aluminium ) , they used in electrical circuits . In electroplating we use metals to coat one metal on another
4. Bad conductors does not allow to pass current through them , so they are used as insulated materials on electric wires . Plastic is coated on copper wire to prevent from electric shocks
hope this helps you mate please mark me as brainliest and please thank my answer!!!!
