When a current I1 = 1.3 A passes through a wire of cross-sectional area A1 = 5 mm2 the drift velocity of the charge carriers is v1 = 2.7  10-5 m/s.
 
  What is the drift velocity of the charges when a current I2 = 0.5 A passes through a wire, made of the same material of cross-sectional area A2 = 3 mm2?
  A)
 
  8.4  10-5 m/s
  B)
 
  6.4  10-5 m/s
  C)
 
  1.7  10-5 m/s
  D)
 
  3.2  10-5 m/s
  E)
 
  2.1  10-5 m/s
