Meaning of Electric Field

What is electric field:

The electric field is a spatial sector that has been modified by the electric charge that, when introduced into it, generates a certain response or reaction.

In other words, the electric field describes the interaction that exists between bodies with an electric charge, which is understood as the level of electricity that the bodies contain.

This interaction can be manifested by the attraction or repulsion between the bodies, depending on the charge they have.

electric field

All the particles that constitute matter have as a fundamental property a certain electric charge, from which the electric field originates.

Electrical charges can be positive (+) or negative (-). Two objects with the same charge repel each other, while objects with different charges attract each other.

The electric field is expressed in imaginary lines that we call vectors. These allow us to get an idea of ​​the intensity and orientation of the electric field.

The electric field is a vector magnitudeof a vector, and not of a force, even though it is intimately related to the electric force.

Electric field units

The elementary unit of the electric field is in the International System (SI) is Newton per Coulomb (N/A).

It is also expressed by the unit of volt per meter (V/m).

Finally, it can be represented in base units as kg m s−3·A−1 and the dimensional equation is MLT-3Yo-1.

electric field lines

electric field lines

It refers to the drawing of imaginary lines whose function is to represent the electric field by expressing its intensity Y orientation.

These lines are characterized by starting from the positive charges towards the negative ones without ever crossing. Likewise, the electric field vector E is tangent to the field line and points in the same direction.

electric field intensity

The electric field intensity, commonly simplified to the expression electric field, refers to the degree of force that is exerted on the unit of positive charge at a certain point.

The formula for calculating the intensity of the electric field is as follows:

In that formula, the arrows represent the vectors. Meanwhile, the letters represent the following concepts:

  • AND: electric field.
  • F: electrical force.
  • what: electrical charge.
