(a) Calculate the conductivity and resistance of a silicon sample. Given that: area = 5 cm2, length = 1 cm, electron mobility = 1000 cm2/(V × s), and number of free electrons = 1 X 1010

cm-3 at 300K. (3 points equation 1 point, correct answer 1.5 points and correct unit 0.5 point)

(b) If we increase the temperature, will resistance increase, decrease or remain same? Explain (1 point)
