Question

write any 2 advantage of AC over DC??



(AC alternate current)
(DC direct current)

Answer 1

DC is mainly used for the maximum current

Answer 2

both AC and DC have loss in long power in lines because the resistance in the wire. For fixed power, higher voltage result in lower current though the power lines and lower current means lower line losses. The earlier engineer realized that the very hight voltage is need for efficient power transmission
