You are presented with several wires made of the same conducting material. The radius and drift speed are given for each wire in terms of some unknown units r and v. Rank the wires in order of decreasing electron current. Rank from most to least electron current. To rank items as equivalent, overlap them. a) radius=3r, drift speed=1v
b) radius=4r, drift speed=0.5v
c) radius=1r, drift speed=5v
d) radius=2r, drift speed=2.5v
