Almost certainly not. Different countries use different voltages and frequencies, but all use AC.Dathascome said:Are there any countries that use primarily DC?
Dath said:I'm sure this is probably not true but this guy I used to work with told me that he thought the big reason we use AC over DC is money. He said things about how for DC the one thing that you really need is just resistors for changing things like voltage. For AC you need all sorts of things like transformers and what not for stepping down/up voltage. He thought it was simply a matter of money, if you need transformers than you need people to make them and you see where this all leads. I can't say, based on my own knowledge whether this is true or not. Maybe someone else here can?
