Electromagnetic Theory #16 Resistance & Capacitance

``` We derive the general resistance formula from field solutions, present capacitance formulas for parallel-plate, coaxial, and spherical geometries, prove the elegant RC = ε/σ relationship, and solve a full numerical example step by step. Topics covered: 0:00 Introduction 0:03 Recap (Poisson's & Laplace's Equations) 0:36 General Resistance Formula 1:35 Capacitance: Three Geometries & RC = ε/σ 3:05 Example: Parallel-Plate Capacitor (step by step) 5:41 Summary Key equations: • R = ∫E·dl / (σ∮E·dS) • C = εS/d (parallel plate) • C = 2πεL/ln(b/a) (coaxial) • C = 4πε/(1/a − 1/b) (spherical) • RC = ε/σ Reference: Sadiku, "Elements of Electromagnetics" 7th Ed., Section 6.5 #ElectromagneticTheory #Capacitance #Resistance #Electrostatics #Physics #Engineering #AcEdumy ```
