16. The figure shows a wire that changes in width, with radii r2 = 2.00 r1. The drift speed in region 1 at the left is 2.00 × m/s. The resistivity is 1.69 x ohm-m. The density of conduction electrons is 8.49 x 3. On the right, length L is 3.00 cm. What is the potential change AV (volts) along that length?


(A) 9.15 ×
(B) 1.37 ×
(C) 3.44 ×
(D) 5.62 ×
(E) 6.83 x
