How do I solve this problem? show steps if possible. thank you!!
While designing an experimental circuit using aluminum wire, you want to limit the current in the wire to no more than 15 A. Remembering that drift speed of conduction electrons is slow, you wonder what the drift speed of the electrons will be under this circumstance. The diameter of the aluminum wire is rather thick at 2.0 cm. The drift speed will be:
O 1.2 x 10-6 m/s O 1.2 x 10-3 m/s O 5.0 x 10-2 m/s O 5.0 x 10-6 m/s O 2.0 x 10-5 rn/s
