i need help on doing cathode protection on nails.can i use electrical wires and attach the positive and nagative sides of a 9 volt battery to two nails?please i need an answer asap.its part of a project where im going to see which is the best way to stop rusting and i was wondering if that will work properly and not cause corrosion instead of protecting the nail from rust?

do i have to say this like 50 times,im doing this as an experiment

I think that you will protect one nail at the expense of the other, so you will both protect one nail and accelerate corrosion on the other.
Since you have not explained the rest of your experimental setup it is hard to be specific.
I think there is a good chance that 9V is excessive, but that might depend on other (unknown to us) factors.
I assume these nails are not being used to hold a wooden structure together, but are just a handy sample of metal?

A cathodic protection system requires that a continuous current can be maintained thru the surfaces that are being protected. Nails are used to join pieces of lumber which are insulators and do not maintain a current flow. I believe that you are wasting your time with this experiment. You would need to protect each nail individually.
Galvanized nails utilize a form of cathodic protection in that the galvanized coating is sacrificed instead of the nail being rusted.

Go to the hardware store and buy galvanized nails. They are made for this purpose.
