A potential difference of 1.0 V is applied across a conductor of length 5.0 m and area of cross-section 1.0 mm2. When current of 4.25 A is passed through the conductor, calculate (i) the drift speed and (ii) relaxation time, of electrons. (Given number density of electrons in the conductor, n=8.5×1028 m−3 ).
a. the drift speed
b. relaxation time, of electrons
