Electric Fields

Title

An electric field is a physical property of space generated by electric charges. It describes how one charge can influence another even at a distance, establishing a direction and intensity of interaction at each point. If a positive charge is placed in a region where an electric field exists, it will tend to move in the direction of the field, while a negative charge will move in the opposite direction.

The electric field allows us to interpret electric forces not as an instantaneous action between separate objects, but as a modification of space produced by charges. In this way, a charge alters the environment around it, and any other charge that enters that region experiences a force determined by the local characteristics of the field.

Electric fields are present in numerous natural and technological phenomena. They participate in the structure of atoms and molecules, in electrical conduction, in the operation of circuits, screens and electronic devices, and even in biological processes related to cell membranes and nerve transmission.
