yes, this is all about the surface area, that is across the wire. |dw:1427222617527:dw| you will have an equation that relates resistance to resistivity via area. this website is usually really good for highlighting the basic principles, not so good this time as normally it has very good illustrations, but you will find "that" formula here: http://hyperphysics.phy-astr.gsu.edu/hbase/electric/resis.html
