1. A current-carrying ohmic metal wire has a cross sectional area that gradually becomes smaller from

one end of the wire to the other. The current has the same value for each section of the wire, so charge

does not accumulate at any one point. (i) How does the drift speed vary along the wire as the area

becomes smaller? (a) It increases. (b) It decreases. (c) It remains constant. Explain

(ii) How does the resistance per unit length vary along the wire as the area becomes smaller? Choose

from the same possibilities as in part (i).
