Expert Answer:
Good conductor have large numbers of free electrons
Poor conductor have very few number of free electron
Good conductor have less resistance to the flow of electric current
Poor conductor have high resistance to the flow of electric current
Good conductor:- Copper and aluminium
Poor conductor:- wood and plastic
