Suppose a current-carrying wire has a cross-sectional area that gradually becomes smaller along the wire so that the wire has the shape of a very long, truncated cone. How does the drift speed vary along the wire? (a) It slows down as the cross section becomes smaller. (b) It speeds up as the cross section becomes smaller. (c) It doesn’t change. (d) More information is needed.
Given Info: current carrying wire having cross sectional area that gradually becomes smaller along the wire so that the wire has the shape of a truncated cone.
Explanation:
Formula to calculate the drift speed is,
