The two wires in the figure (Figure 1) are made of the same material. What is the current in the 2.0-mm-diameter segment of the wire? What is the electron drift speed in the 2.0-mm-diameter segment of the wire?

Final answer:

To find the current and drift velocity in a 2.0-mm-diameter segment of a wire, you can use the formulas I = v * A * n * q and v = I / (A * n * q), respectively.

Step-by-step explanation:

The current in a 2.0-mm-diameter segment of a wire can be calculated using the formula: I = v * A * n * q. Where: I is the current, v is the drift velocity of the electrons, A is the cross-sectional area of the segment, n is the charge carrier density, and q is the charge of an electron.

The drift velocity in the 2.0-mm-diameter segment of the wire can be determined using the formula: v = I / (A * n * q). By substituting the given values into these formulas, you can find the current and drift velocity.
