Meaning of Electric Field - encyclopedia - 2023



What is Electric Field:

The electric field is a space 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 bodies contain.

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

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

Electric charges can be positive (+) or negative (-). Two objects of the same charge repel each other, while those of different charge 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 about a vector magnitude, of a vector, and not of a force, even when it is closely related to the electric force.

Units of electric field

The elemental unit of the electric field is in the International System (SI) is Newton by Coulomb (N / C).

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

Finally, it can be represented in basic units as kg · m · sβˆ’3·TOβˆ’1 and the dimensional equation is MLT-3I-1.

Electric field lines

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

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

Electric field strength

Electric field intensity, commonly simplified to the expression electric field, refers to the degree of force exerted on the unit of positive charge at a given point.

The formula to calculate 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.
