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 Field Definition. An electric field is a region of space in which an electric charge “feels” a force. Electric field strength at a point is defined as: The electrostatic force per unit positive charge acting on a stationary point charge at that point. Electric field strength can be calculated using the equation: Where:
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.
