Question

Hi,

I am having trouble answering the following physics question.

The two wires in the figure are made of the same material.

a) What is the current in the 2.0-mm-diameter segment of the wire? Express your answer with the units A.

b) What is the electron drift speed in the 2.0-mm-diameter segment of the wire? Express your answer with the units ?m/s.

Any help you can provide would be very much appreciated.

Explanation / Answer

a)

Charge is conservative, therefore,

I = 2.0 A

b)

v2/v1 = A1/A2

v2 = (d1/d2)^2 v1 = (1/2)^2 * 2e-4 = 5e-5 m/s
