The project I am working on specifies a 12v 0 12v centre tapped transformer. I have a 12v twin secondary left over from a previous project. My plan is to wire the two secondaries in series in order to form a centre tap, as per this thread:
My question is, I think this will double the voltage to 24v - is that correct? The project specifies 12v, so would I be better using a 6v twin secondary transformer with the secondaries wired in series?
I am a wee bit confused since a similar question was asked here:
The advice given was, "If you can't find a 12V centre tapped transformer, use a 12V transformer with twin secondaries and connect them in series"
I would be very grateful if someone could clarify.
