why cant we charge a conductor by rubbing or by contact with a charged insulator?

Expert Answer
Because, insulator by definition does not allow the flow of charges. So, even though the insulator might be charged, it will not pass any charge to the conductor on either touching it or rubbing it. So, conductor can't get charged by conduction.
However, it would be possible to charge conductor by induction. If the charged insulator is just brought near the conductor, it will induce a rearrangement of charges in the conductor such that the face of the conductor near insulator gets oppositely charged.
