Advantage and disadvantage of AC over dc
ADVANTAGES
The generation of A.C. is cheaper than that of D.C
.A.C. machines are simple , robust and do mot require much attention for their repairs and maintainance during their use.
Wide range of voltages are obtained by the use of transformer.
The magnitude of current can be reduced by using an inductance or a conductor without any appreciable loss of energyA.C. can easily be converted into D.C. with the help of rectifiers.
When A.C. is supplied at higher voltages in long distance transmission , the line losses are small compared to a D.C. transmission
DISADVANTAGES
Peak value of A.C. is high and it is dangerous to use so better insulation is required. It attracts person who touches it unlike D.C. which gives a repelling shock.
An A.C. is transmitted from surface of the conductor and hence need several strands of thin wires insulated from each other.
