5. Determine the capacitance of a capacitor needed to store 1 kWh if it is charged to 500 V. [10 marks] 6. Compare the average thermal velocity of an electron, V₁, at room temperature, if mv2 = 1/2kT, where m is the electron mass, k is Boltzmann's constant and T is the absolute temperature, with the drift velocity of an electron having a mobility of 103 cm² /volt-sec in an electric field of 1000 V/cm. The drift velocity equals the product of the mobility and the electric field. At what electric field strength will the drift velocity equal the thermal velocity? [10 marks]
