We have a copper conductor, length l = 1m and circular section of diameter d = 4mm a) Calculate the resistance of the conductor between its ends. b) If a current of 1 amp flows through said conductor: I) Calculate the drag speed of the electrons. II) calculate the number of electrons per second that cross the conductor section. Data: resistivity of copper PCu = 1.7 × 10-8 -8 ampere m: numerical density of charge carriers [nCu] = 8.5 × 1028 atoms m-3: resistivity of aluminum p Al = 2.8 × 10-8 ampere m elemental load = 1.6x10-19 C
