A cylindrical copper wire has a resistance. If then you're told that the length of the wire is doubled but that the volume is to be kept the same, what happens to the resistance? By that I mean, what factor does the resistance increase or decrease by, if any, and explain your reasoning. Hint: If the length changes and volume stays the same, something must happen to the cross-sectional area.
