This is a mouthful! I have a copper pipe fixed with zink coated (galvanised) saddles.
- I want to ascertain what the voltage would be in the dissimilar metal galvanic reaction between zinc and copper? Looking at the tables is confusing to me because the values given for copper is +0.34V but 0.34V in relation to what? is that the voltage relation between copper and Stainless steel or Copper - Tinanium or Copper - Zinc, I dont know?
- Would the surface area influence the voltage or potential difference between the metals?
- If so, how would I determine the voltage produced per square surface of the metal faces. I have 10 sq cm surfaces of the metals in contact with each other.
- How would I then calculate the current strength between the two metal surfaces?
Thank you for any help with this!
