The force acting on a particle placed in the field is called an electric field.
The Newton/Coulomb, or , is the unit of measurement of the electric field.
The direction of the electric field corresponds to the direction of the force vector for positive charges .
Charles Coulomb experimentally proved the basic principle of the electric force between two stationary charged particles in .
For the electric force between two charges, Coulomb proposed the following mathematical representation. Charges and are separated by a distance , and the magnitude of the electric force between them is given by, , where known as Coulomb constant.
An electric field is created when a charge moves through a space, and this field acts as a force on other charges. The force that an electric field experiences with a positive charge is its intensity. It can be called as:
The electric field is, in fact, a manifestation of electromagnetic force. One of the primary forces in nature is electromagnetic force.
