Advantages and disadvantages of AC over DC
There are many advantages and disadvantages of AC system over DC system.
(i) The generation of AC is cheaper than that of DC.
(ii) When AC is supplied at higher voltages, the transmission losses are small compared to DC transmission.
(iii) AC can easily be converted into DC with the help of rectifiers.
(i) Alternating voltages cannot be used for certain applications e.g. charging of batteries, electroplating, electric traction etc.
(ii) At high voltages, it is more dangerous to work with AC than DC.
