1. The problem statement, all variables and given/known data Estimate the resistance of a gold (wedding-type) ring. State clearly all assumptions, and introduce any equations you use. your solution should also include a brief summary of how you approached and solved the problem. Helpful tip: You will have to make certain assumptions. My professor is not looking for one particular numerical answer. Any reasonable approximations will be acceptable. 2. Relevant equations I have the Resistance equation. 3. The attempt at a solution We have to make assumptions. I would need to lookup the resistivity of gold. Not sure though how to do it though if it is 50% copper as well. If it was 100% gold, you would lookup the resistivity of gold, the length of gold ring (L), and figure out the area. I would make an assumption for the radius. This would be a cross-sectional area I believe. I'm not really sure what some reasonable L, and R values are. Also, what would you say about being 100% gold vs 50% copper and 50% gold?
