Poisson's equation is a partial differential equation named
after the French mathematician and physicist Simeon-Denis
Poisson. Derived from Coulomb's law and Gauss's law, it is a
second-order partial differential equation used for solving
problems, such as finding the electric potential for a given
charge distribution, or modeling gravitational fields. It is
commonly used in the fields of electrostatics, mechanical
engineering, and theoretical physics. Chegg is for students See
