Question

4) (15 points) The figure shows a steady electric current passing throug with a narrow region. What happens to the drift velocity of the moving they go from region A to region Band then to region C? Explain wrs charges as choice your A) The drift velocity decreases from A to B and increases from B to C B) The drift velocity increases all the time. C) The drift velocity remains constant. D) The drift velocity decreases all the time. E) The drift velocity increases from A to B and decreases from B to C

Explanation / Answer

Correct answer: Option (E) : The drift velocity increases from A to B and decreases from B to C

Using formula: A1 v1 = A2v2

area from A to B decreases and B to C increases
