Electrical field

An electric field is a vector field that associates to each point in space the Coulomb force that would be experienced per unit of electric charge, by an infinitesimal . BufretLignendeOversett denne sidenElectric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test .

We can think of the forces between charges as something that comes from a property of space. The electric field from a positive charge points away from the charge; the electric field from a negative charge points toward the charge. In the previous section of Lesson the vector nature of the electric field strength was discussed.

The magnitude or strength of an electric field in the space . In the previous section of Lesson the concept of an electric field was introduced. It was stated that the electric field concept arose in an effort to explain . One of the fundamental principles that must be understood in order to grasp electric circuits pertains to the concept of how an electric field can influence charge .

Electric fiel an electric property associated with each point in space when charge is present in any form. The magnitude and direction of the electric field are . This tutorial introduces electrical fields in physics. Other sections include motion, heat, magnetism, light, and modern physics.
