Answer
(a) At the generating station, the electric power is generated at a voltage of 11 kV because generation at voltage higher than 11 kV causes insulation difficulties, while generation at voltage lower than 11 kV involves a very high current.
Hence, electric power from the generating station is transmitted at 11 kV.
(b) The nature of current transmitted from the power station is alternating current (a.c.).
