The material which allow them to pass elactric current or heat is called conductor .When the conductor will touch a metal that allow them to pass the electric current will pass within 30 secs

Answer:
Electrical resistance of a conductor may be defined as the basic property of any substance due to which it opposes the flow of current through it. We know that current is inversely proportional to resistance. i.e. greater the current less is the resistance and vice versa. Therefore, resistance of a conductor will increase in (i) while resistance of conductor will decrease in (ii).
