(i) An uniform copper wire has a resistivity of 1.54 x 10* ohm-meter at room temperature. For an electric field along the wire of 1 Volt/cm, compute the mobility and average drift velocity of the electrons, assuming that there are 5.8 x 10% conduction electrons/m. Also calculate the relaxation time of the electron.
