8.A transformer is to be designed to increase the 40-kV (rms) output of a generator to the transmission line voltage of 400 kV (rms). If the primary winding has 100 turns, how many turns must the secondary have? What is maximum current to the transmission line if in the primary winding current is 40 A.?
