17 lut 2023 · An electric field is an invisible force field caused by an electric charge. It is an alteration in the space (air or vacuum) around the charge. It results in an electric force that is felt by electric charges when placed close to one another.

Electric-Fields-Potentials.Electric-Fields.LO.CB.2.C.1.1: The student is able to predict the direction and the magnitude of the force exerted on an object with an electric charge q placed in an electric field E using the mathematical model of the relation between an electric force and an electric field: F ⃗ = qE F → = q E →; a vector ...
Arrange positive and negative charges in space and view the resulting electric field and electrostatic potential. Plot equipotential lines and discover their relationship to the electric field. Create models of dipoles, capacitors, and more!
We would have to calculate the sum of the forces from scratch. Fortunately, it is possible to define a quantity, called the electric field, which is independent of the test charge. It only depends on the configuration of the source charges, and once found, allows us to calculate the force on any test charge.
To explain the phenomenon of an electrical environment consisting of a system of charges, we use the term Electric Field. It is very useful in determining the amount of electric force applied to a unit test charge inside the system.
19 maj 2021 · This is called Coulomb’s law. Equation (16.1.4 16.1.4) is the electric equivalent of Newton’s universal law of gravitation. Replacing mass by charge and G by −1/(4πϵ0) − 1 / (4 π ϵ 0) in the equation for the gravitational force between two point masses gives us equation (16.1.4 16.1.4).
