Gauss’s Law Explained: Derivation From Coulomb’s Law

May 15, 2015/3 Comments/in Electromagnetism, Physics Tutorials/by Minjie Lei

Gauss’s law states that the total electric flux through any closed surface equals the total enclosed charge divided by the permittivity of free space (ε₀). Carl Friedrich Gauss formulated the law in 1835, and it is one of the four Maxwell’s equations underlying classical electrodynamics. It is mathematically equivalent to Coulomb’s law and can be…
