suppose a cylindrical conductor is kept horizontally and an electric field is applied.
now the positive charges will start to move in the direction of the field and the negative charges in opposite dir. and a new electric field will be generated inside.
this field will appose the initial electric field ..... right...
then how is current able to pass in such conductors for a very long time...i mean a conductor of this form is used to provide electricity..... then shouldn't the potential dec. with inc. in time them how is a uniform current provided.....
plz
help
rates assured
