An aluminum wire 1.024 mm in diameter (18-gauge) carries a current of 2 amps. a. What is the number density of charge carriers (electrons) in the wire? The number density of electrons in the wire is m31​.  (Use "E" notation to enter your answer in scientific notation. For example, to enter 3.14×1012, enter "3.14E12".) b. What is the magnitude of the drift velocity of the electrons? The drift velocity of the electrons is vd​= m/s c. What would be the drift velocity if the same gauge copper were used instead of aluminum? For the same gauge copper wire, the drift velocity would be vd​= m/s There is a disconnect between how small drift velocities are and how quickly electrical signals travel through wires (nearly at the speed of light). For the moment, treat the two as completely unrelated to each other.
