why do power stations generate ac and not dc

Because AC is easy and cheap to transform from one voltage to another using transformers. High voltage means less amperage for the same power, meaning you can do with thinner wires. ... So high voltage DC transmission lines are now becoming more popular. DC has the advantage that you have no losses due to EM radiation

Compare to AC (alternating current) the DC (direct current) is much more efficient in various aspects.
Some of them are listed below:
- A rotating conductor turns in a magnetic field. It can produce only AC (alternating current); and not DC (direct current).
- Compare to (direct current) the transmission of electricity is simpler and far more efficient with AC (alternating current).
- This is because the transformers can give step up and step down voltages as required.
