because power dissipated in ac is less than power dissipated in dc.
AC power can be transmitted more efficiently than DC.
yes it is 230 v is deadly, it doesn't matter if it's ac or dc. Some people say one is more dangerous than the other. That implies that there is some voltage, lower than 230 v, at which one will kill you but the other will not. There is no conclusive evidence for that, so it can't be said that ac is more dangerous than dc or vice versa.
AC is preferred over DC in most electrical power distribution systems because it is easier and more cost-effective to generate, transmit, and distribute over long distances. AC can be easily converted to different voltage levels using transformers, making it more efficient for power distribution. Additionally, AC allows for the use of alternating current motors, which are more reliable and cost-effective than DC motors for industrial applications.
Ac/dc
DC motors are generally more efficient than AC motors. DC motors have a lower amount of inertial associated with them, making them more efficient to run.
The power source is AC. Hence AC is used. DC application is limited.
That is a matter of personal preference, they have sold more albums/CD's than KISS.
Ac dc
a.c is more danger than d.c
Both bands compete in terms of fame, but Back in Black by AC DC sold more than any of Zeppelin's albums.
AC only. That's one of many reasons why AC is more useful (and more widely used!) than DC.
AC DC sold more albums in general than Metallica did, so AC DC is more popular; plus, AC DC's music is much more fun, Metallica's music is kind of annoying after awhile.
