Poisson's equation

Poisson's equation is a mathematical formula that describes how the distribution of electric charge affects the electric potential in a region. In simpler terms, it relates the presence of charge, like how densely charges are packed in a space, to the resulting electric field and potential energy in that area. This equation is fundamental in fields like physics and engineering, helping to understand various phenomena such as electricity, gravity, and fluid dynamics. It shows how sources of force (charges or masses) create effects (fields or potentials) in their surroundings.
