Web1. Yes, there is a standard Poisson, the one with parameter 1. Recall that if X counts the number of "accidents" in a unit time interval, then under suitable conditions X has Poisson distribution with parameter the mean number of accidents per unit time. If that parameter is λ, then the number of accidents in a time interval t is Poisson with ... http://www.uoxray.uoregon.edu/ph353/Poisson_distribution.pdf

WebMay 9, 2024 · We get Poisson's equation by substituting the potential into the first of these equations. − ∇2V = ρ / ϵ0. ρ is zero outside of the charge distribution and the Poisson equation becomes the Laplace equation. Gauss' Law can be used for highly symmetric systems, an infinite line of charge, an infinite plane of charge, a point charge.
