Specialty Definitions: Electric Field

Domain	Definitions
Aerospace	1. A region in which a charged particle would experience an electrical force; the geometric array of the imaginary electric lines of force that exist in relation to points of opposite charge. An electric field is a vector field in which magnitude of the vector is the electric-field strength and the vector is parallel to the lines of force.2. = electric-field strength. See atmospheric electric field. (references)
Space	The region in which electric forces can be observed, e.g. near an electric charge. As a field, it may also be viewed as a region of space modified by the presence of electric charges. (references)

Specialty Definition: Electric field

(From Wikipedia, the free Encyclopedia)

In physics, an electric field is the effect produced by the existence of an electric charge, such as an electron, ion, or proton, in the volume of space or medium that surrounds it.

The mathematical definition of the electric field is developed as follows. Coulomb's Law gives the force between two point charges as

This was known empirically (note - the equation is given for SI units). Suppose we take one of the charges to be fixed, and the other one to be a moveable "test charge". We note that according to this equation, the force on the test object is proportional to its charge. We define the electric field to be the proportionality constant between charge and force:

Hence, electric field is dependent on position. A field, in this context, means a vector which is dependent on another vector - a vector valued vector function.

Another empirically known fact was that in the presence of a more complicated fixed object, the electric forces from the constituent charges can simply be added together. Hence, the electric field due to a composite object becomes

where E₁, E₂, etc. are the electric fields due to individual charges making up the object. This is what is meant when it is said that the electric field is "linear". For a continuous distribution of charge (rather than discrete points), we can define the electric field to be:

where ρ is the charge density - i.e. charge per unit volume.

See Maxwell's equations for the full set of equations governing electric fields.
