Answer / anitha

* AC proved to be cheaper and easier to transmit the power of alternating current over long distances

* AC can be stepped up or down using transformers

Answer / subbarayalu

some of the advantages of AC over DC are
1) it can be stepped up or stepped down in voltage
2) it can be transported to longer distances
3) it can have least loss power loss due to heating.
4) it is easier and cheaper to produce
5) it is economical to trasport. etc.,
6) it is easy to design equipment
7) size of the AC machine will be small

Answer / anjan

1.generation of ac is easy
2.transmition of ac is economical upto 240kv
3. designing of switch gear is easy

Answer / adnan kauchali

The main advantage of AC over DC is that it can be easily
steeped up or stepped down using static
machines(Transformer). The power can either be increased to
extra high voltage for long transmission or stepped down to
the safe voltage for consumer use.
Except these there are several advantages of AC power

Answer / guest

generation is easy,calculation is easy.

how we control automatic generator i'e with to supply (main supply and local generator) when the main supply was break to supply the local supply automatically to begin supplying power.I now this control circuit is the combination of contactor time delay contactor switch and overload relay .but my question is how we combine those component thank you
