The area specific resistance

WebElectrical resistance is also known as specific electrical resistance. The SI unit of electrical resistivity is Ωm. Following is the formula of electrical resistivity: ρ = E J. Where, ρ is the resistivity of the material in Ω.m. E is the electric field in V.m -1. J … WebIn the frame of the ZeuS-III project, a model study was started on evaluation the area-specific resistances (ASRs) of various layers being used in SOFC stacks. It is well known that stack performance not only depends on cell resistance but also on the electrical conductivity of the various applied contact and protective layers.

WebThus, the specific cake resistance equals the pressure difference required by the liquid phase (with a viscosity of 1 N-s/m ) to be filtered at a rate u = 1 m/s for a cake 1 m thick. This hypothetical pressure difference is, however, beyond a practical range. For highly compressible cakes, the value ro reaches 10 m or more. WebJan 24, 2024 · We know that the electrical resistance \(R\) and specific resistance \(\rho \) depend on the physical nature of the given material; its dimensions or physical shape are expressed in terms of its length \(L\) and area of cross-section A. Thus, the conductance of a material is a function of the nature and physical properties of the given substance.
