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

Dashawn Maynard · Answer 1

d > a > b > c

Explanation:

Given that

a) radius = 3r and drift speed = 1v

b) radius = 4r and drift speed = 0.5v

c) radius = 1r and drift speed = 5v

d) radius = 2r and drift speed = 2.5v

Based on the above information, the ranking of the wires for reducing the electron current is

As we can see that the radius i. e to be less and the drift speed that is highest so it should be rank one

And, According to that, other options are ranked

Therefore, the ranking would be d > a > b > c
