The formula for electrical resistance is R=voltage/current and measures a materials resistance to the passage of electricity. I have handstamped this formula (using an Omega for Ohms) in a brass disc along with the positive/negative symbols. Underlying the brass disc is a second larger disc of copper that has been stamped with a bunch of x's. Perfect for a physics major, electrical engineer or geek in your life!

* Copper and Brass discs
* Handstamped resistance formula - unique and nerdy!
* 16" copper ball chain

A note about COPPER:
Copper is a reactive metal and will oxidize over time to a darker color. The bright finish can be extended through the use of wax or lacquer, such as clear nail polish, if you don't like the natural darkening that will take place over time. I use museum quality preserving wax on all my copper/brass creations, but this is not a permanent treatment. I suggest cleaning your copper pieces using very fine steel wool or a polishing cloth of some kind. If you get a skin reaction from wearing copper, your best bet is a light coat of clear nail polish on the item to protect your skin. Please consider the reactivity of the metal and potential maintenance of items before you purchase any of my 100% pure copper creations.
Thank you.

ATTENTION!!! This is a 100% hand stamped item. I use an anvil and hammer to create each piece and no two are exactly alike. There can be variations in alignment and depth of images and other imperfections that are a result of me not being a machine. If you are looking for machine crafted perfection I am afraid my humble little creations may not be for you. Please consider this before you buy. Thanks.
