Electric Field
An electric field is a force which surrounds around electric
charges that attracts or repels another electric charge. Mathematically the
electric field is a field that associates to each point in space, titled the
Coulomb force, that would be skilled per unit of charge. The units of the
electric field in the SI system are newtons per coulomb (N/C), or volts per
meter (V/m). Electric fields are created by electric charge in electric circuits.
According to microscopic analysis, the electric field is an attractive force
between the nucleus and the electrons that holds atoms together, and the forces
between atoms that create chemical bonding. The electric field and the magnetic
field form the electromagnetic field.
According to Coulomb's Law
The Coulomb force on a charge of magnitude at any point in space is equal to the
product of the charge and the electric field at that point
F=q*E
Unit of Electric Field
The units
of the electric field in the SI system are newtons per coulomb (N/C), or volts per meter (V/m); in terms of the SI
base units they are kg⋅m⋅s−3⋅A−1
Causes of Electric Field
Car fields are caused by motorcar charges, described by Gauss's
law, or varying attractable fields, described by Faraday law of induction.
Together, these laws are enough to delimitate the action of the electric field
as a function of electric field. the equations of both fields are relative to
the Maxwell's equations that describes both as a function of charges and
currents.
According to Gauss's Law and Faraday's Law
In the special case of a steady state the Maxwell-Faraday inductive effect disappears. The resulting two equations
(Gauss's law
)
with no induction term taken together, are equivalent to Coulomb's law
written as for a charge density. Notice that the permittivity of vacuum,must be substituted if charges are considered in non-empty media.
