okk cool thanks again my exam went pretty good there was only one question about ac vs dc and it was why is ac used to transmit electricity over long distances rather than dc? And i think i put a good enough answer for that question at least:) so thanks again.. multiple choice was a little...

oh i see cool thanks for the info...hopefully this will help me for my exam tomorrow :O LOL..

ok thanks ... but i also hear that many things that run DC are more expensive... then AC...why is that?

ok thanks guys but then why use dc at all...like why do many thigns use dc? instead of ac like many computers and other electronics

Can someone explain breifly or in detail :biggrin: the differnece between ac and dc. Maybe advantages and disadvantages. From what i have researched i know that ac the current flows in every direction while in dc it only flows in one. In ac the voltage can be put down and up using transformers...
