Q: Two power outlets in series... by A3.
Hi, can I connect two 110v outlets in series to double the voltage?

by cornell.edu
If you were to try connecting the positive to negative points from one socket to another and then connecting the free ends to an appliance you would probably blow a fuse.
All of the sockets in a house are from the same outside source which means that if you connect the positive end of one to the negative end of another that would create a short circuit with the outside transformer, thus blowing a fuse and possible starting a fire.
The best thing to do would be to SAFELY (contact an electrician for details) connect your appliance to a voltage doubling transformer and then connecting that to the outlet. It's also possible that your refrigerator or oven outlet has 220 volt AC.
Good luck,
