conductors are the substance that has mobile electrons which
moves from one atom to another CONSTANTLY(juz imagine line
of people passing the ball constantly as they get the ball

which the electrons does'nt move readily unless it is
doped(here distance between the people is large,so people
become lazy to pass the ball...this is case for undoped ..)
