Electromagnetic Theory #17 Method of Images

``` We introduce the method of images, a powerful technique that replaces conducting surfaces with equivalent image charges to solve electrostatic problems through simple superposition. We derive the potential, electric field, and induced surface charge for a point charge above a grounded plane, present the wedge geometry formula, and work through a complete example with two 90-degree planes. Topics: 0:00 Introduction 0:03 Recap (BVP Approach, R & C) 0:24 Method of Images: Concept & Setup 1:27 Formulas: V, Surface Charge, Wedge Geometry 3:09 Example: Charge Between 90° Planes (step by step) 5:32 Summary Key equations: • V = Q/(4πε₀) [1/r₁ − 1/r₂] (point charge + image) • ρₛ = −Qh / 2π(x² + y² + h²)^(3/2) • Q_induced = −Q • N_images = 360°/φ − 1 (wedge geometry) Reference: Sadiku, "Elements of Electromagnetics" 7th Ed, Section 6.6 #ElectromagneticTheory #MethodOfImages #Electrostatics #Physics #Engineering #AcEdumy ```
