### How is Poisson’s equation related to Laplaces equation?

Poisson’s equation. It arises, for instance, to describe the potential field caused by a given charge or mass density distribution; with the potential field known, one can then calculate gravitational or electrostatic field. It is a generalization of Laplace’s equation, which is also frequently seen in physics.

**How to find Poisson’s equation for electrostatics?**

Electrostatics The laws of electrostatics are ∇.E = ρ/ 0 ∇×E = 0 ∇.B = 0 ∇×B = µ 0J where ρand J are the electric charge and current ﬁelds respectively. Since ∇ × E = 0, 0 gives Poisson’s equation ∇2 0. In a region where there are no charges or currents, ρand J vanish. Hence we obtain Laplace’s equation ∇2Φ = 0.

#### How is Poisson’s equation used in Mechanical Engineering?
