1. The problem statement, all variables and given/known data Two conductive metal plates are bonded together. Upon bonding, an oxide layer forms between them. The oxide layer is negligible thus the overall resistance of the plates is small. However I am having trouble finding this overall resistance, i.e., trying to find Cp and Rp. Dimensions and properties of M1,M2, and the oxide layer are known. Oxide thickness << M1 and M2 thickness 2. Relevant equations Parallel plate capacitance equation: C = epsilon A / t Wire resistance equation: R = rho L /A Loss tangent of capacitor and quality factor to get the parallel resistance 3. The attempt at a solution The resistance of the oxide layer is high but how do I apply this to the overall resistance? The attached image shows my work. Thanks gents.
