Hello
i need a 9VAC 1.3A source but it's hard to come by... is there a way i can use a similar source?
i don't know too much about this sort of thing but from what i understand the power output is more important than the individual current or voltage out... is that right? for example, my source would have to be around 12W output (p=iv=1.3*9=11.7watt.) or does the current and voltage rating actually matter?
could i add a resistor to say a 12vac 1a source to drop the voltage to get what i need?
what about vac verses vdc; does this really matter? if my wall socket output is 3p anyway, isn't that like vdc since it's constant?
i'm confused, any help would be much appreciated!
