Zinc and copper, steel and copper, steel and zinc, which is better? and why? in description.. please help, thank you :)
Copper and zinc. This is because the voltage created by two electrochemically dissimilar metals is the difference between the anodic values of the metals. To create the highest voltage, you will need to combine the metal with the lowest anodic index value, with the metal with the highest anodic index value. This will give the highest voltage. In the case of copper and zinc it will be around 0.9 volts. Copper = .35 volts Steel = .6 - .85 volts (depending on the type of steel) Zinc = 1.25 volts
Zinc and Copper - More electrically conductive than the other 2 options. Steel is usually used as an electrical conductor when there are mechanical forces at play that could lead to structural fatigue since it is a stronger metal (like in cars or airplanes, or in buildings to resist rats chewing through it). For a stationary project like this, Zinc and Copper.
