I Know that this is a dumb question but, I am curious anyway.
Lets just say that I need an 18 volt DC power source and that the source has to come from one of those transformers? that plug into the wall and change AC to DC.
What if I only have two of those transformer devices that are 9 Volts DC each.
Now, If I cut the insulation off of the ends of both of those transformers, take the two wire ends from each and twist the 4 ends together to make two again, plug them in, will THAT make me the 18 volts that I need?9 + 9 makes 18 doesn't it?
PLEASE tell me that I have made SOME sense here?
Thank You Brenda
