3) conductor is the material which allows the current to flow through it.
example:- copper, silver
4) insulators are the poor conductors of electricity but with very high resistance.
example :- glass, plastic, rubber
5) semi conductors are crystalline with electrical characteristics they are of high resistance.
6) acts to environment are
* (clean air Act , clean water act, clean toxic substances) acts the laws made by United States government in 1970s
