Question

When a potential difference of 1.5V is applied across a wire of length 0.2m and area of cross section 0.3mm2, a current of 2.4A flows through the wire. If the number density of free electrons in the wire is 8.4 x 1028 m-3 , calculate the average relaxation time. Given that mass of electron = 9.1 x 10-31 kg and charge on electron = 1.6 x 10-19 C​
