why do power stations generate ac, and not dc ?
the reason why power stations generate ac, and not dc, is because
a. it is easier to generate, safer, and more economical to transmit ac than dc.
alternating current or ac and direct current or dc are types of current flow in a circuit. power stations generate ac because of its advantages over dc. few examples are:
1. large electrical generators happen to generate ac naturally, so conversion to dc would involve an extra step.
2. transformers must have alternating current to operate, and we will see that the power distribution grid depends on transformers.
3. it is easy to convert ac to dc but expensive to convert dc to ac, so if you were going to pick one or the other ac would be the better choice.
