Overview
Electrostatics is the study of electric charges at rest, the forces between them, and the effects they produce in terms of electric fields and electric potentials. This fundamental branch of physics helps us understand phenomena from lightning strikes to the working of photocopiers. The chapter cove
Key Concepts
Basic property of matter carried by
Basic property of matter carried by protons (+1.6×10⁻¹⁹ C) and electrons (-1.6×10⁻¹⁹ C). Charges can be transferred by friction (conduction) or induce
F = (1/4πε₀) × (q₁q₂/r²)
F = (1/4πε₀) × (q₁q₂/r²) for charges in vacuum. Force is attractive for unlike charges, repulsive for like charges. In medium: F = (1/4πε₀εᵣ) × (q₁q₂/
Electric field E = F/q₀ represents
Electric field E = F/q₀ represents force per unit positive test charge. For point charge: E = (1/4πε₀) × (Q/r²) r̂. Practical definition: E = V/d betw
Imaginary curves whose tangent gives field
Imaginary curves whose tangent gives field direction at any point. Properties: originate from positive charges, terminate on negative charges; never i
∮E⃗·dS⃗ = Q/ε₀
∮E⃗·dS⃗ = Q/ε₀. Electric flux through any closed surface equals enclosed charge divided by ε₀. Flux φ = E⃗·S⃗ for uniform field. Independent of surfac
