6. You take a copper wire as shown in the figure, where the cross-section area A doubles between parts. 1 and 2 of same length, and apply a potential difference across it so that a current flows from part 1 to 2. What happens in part 2 of the wire, as compared to part 1?" r OS X A) The electron current increases B) The electron density increases C) The resistance increases D) The electric field or drift speed decrease E) The electric field and drift speed decrease F
