Electric field
Storyboard 
As loads generate forces, a load distribution will act on a load that positions one at any point in space. In other words there is a 'field' that is a force at any point in space. This force depends on the charge we expose, so it makes sense to define a force per charge so that it is independent of the particle's charge that we seek to study its behavior. Therefore it is possible to define what we call an electric field that is the total sum of all Coulomb forces of the distributed charges divided by the charge of the particle from which the behavior is being studied.

The force ($\vec{F}$) on the test charge ($q$) at the position ($\vec{r}$) will depend on the number of charges ($N$), indexed by $i$ and represented by the charge of the ion i ($Q_i$) located at the position of a charge i ($\vec{u}_i$). With the parameters the dielectric constant ($\epsilon$) and the electric field constant ($\epsilon_0$), this can be written as:
With the definition of the electric field ($\vec{E}$) given by
it follows that the electric field of a charge distribution is
The magnitude of the force with constant mass ($F$) generated between two charges, represented by the test charge ($q$) and the charge ($Q$), which are at a distance of the distance ($r$), is calculated using the electric field constant ($\epsilon_0$) and the dielectric constant ($\epsilon$) as follows:

Examples
To measure Coulomb's force, a test charge must be introduced into the system. If this test charge is the test charge ($q$), the force per unit charge exerted by the system's charges on the test charge can be estimated. The magnitude of the force the force ($\vec{F}$) per unit charge the test charge ($q$) is called the electric field the electric field ($\vec{E}$) and is measured in Newtons (N) per Coulomb (C). The electric field is measured under the assumption that the test charge does not significantly disturb the system; in other words, it is assumed to be very small. The definition of the field can be written as:
In the case where the geometry allows for one-dimensional analysis, the force with constant mass ($F$) per the test charge ($q$) can be defined by introducing the electric eield ($E$), which is expressed as:
