Why ac instead of dc?

Answer 1

ac transmission are used because we easily step up the voltage as per our requirment and also breaker used for ac break the ac current easily bcs of nature of zero current at every cycle

but for long distance transmission done by dc due to reducing the skin effect and also reduce the relative inductance of the line due to this the line losses are reduce and we transmit the more power.

Answer 2

Why transformer rating is measured in KVA but not in KW

Answer 3

Ac/dc is a band, ac is air conditoning, and an acto dc converter has something to do with electricity

Answer 4

ac refers to alternating current and dc represents for direct current. in ac current, its frequency changes with time whereas in dc its frequency doesn't change with time.

Answer 5

the difference between ac and dc is that the curren on ac is moving alternative and on dc is moving directly
