why is alternating current preferred over direct current List any three reasons
Answers
1.The biggest advantage AC has is that you can step up or step down AC voltage relatively easily using a device known as the transformer.
2.Transmitting power over large distances requires you to choose a higher voltage level. This has something to do with power system stability.
3.Using higher voltage levels helps in reducing power losses on transmission lines since for a fixed amount of power, you require less current.
Since DC does not have the capability of stepping up / stepping down voltages until very recent times, AC is preferred.
Answer:
There are three logical reasons to prefer alternate current (AC) is over Direct Current (DC). The reasons are: it is easy to maneuver and maintain. Secondly, it is easier to change the voltage of AC for transmission as well as for distribution. Thirdly, Alternative Current has lower losses as it is easier to step up or step down the AC voltage easily.
