The space surrounding an electric charge or in the presence of a time-varying
magnetic field has a property called an electric field. This electric field exerts
a force on other electrically charged objects. The concept of an electric field
was introduced by Michael Faraday.
The electric field is a vector field with SI units of Newtons per coulomb (N/C)
or, equivalently, volts per meter (V/m). The SI base units of the electric field
are (kg·m) / (s3·A). The strength of the field at a given point is defined
as the force that would be exerted on a positive test charge of +1 coulomb placed
at that point; the direction of the field is given by the direction of that force.
Electric fields contain electrical energy with energy density proportional to the
square of the field intensity. The electric field is to charge as gravitational
acceleration is to mass and force density is to volume.
