Will This Work?

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

It can work if you connect them correctly. Either you get 18V if wired
correctly or you get nothing if you connected them wrong.

transformer devices...9 Volts DC each.

and the maximum current you can pull is the rating of the smaller unit
(assuming they're not equal).

Yep. Just wire them both in series.

Just like stacking batteries in your flash light...;o]
