Conductors are substances that contain free electrical charges. Due to the presence of free charges in presence of electric field, the electrostatic field inside the conductors is zero. Indeed, if there was an electric field inside the conductor, then a current would arise. It appears, for a very short time, when an Read more…
Already the first serious researchers of electricity and magnetism became convinced that electromagnetic oscillations these phenomena are interconnected: currents of charged particles create a special field in the space surrounding them, called magnetic. In turn, magnetic fields can be recorded by observing their effect on electric charges. Many experimentally observable facts Read more…
The dielectric, when exposed to an electric field, is polarized: electric charges are induced on its surfaces. If the electric field is increased, then at a high voltage breakdown of the dielectric occurs, its structure changes, and an electric current appears. What is polarization? When an external electric field acts on Read more…
Coulomb’s Law is one of the fundamental laws in physics. He examines the forces of interaction between two charged objects. As the distance between them increases, the force interaction and the characteristics of the electric field decrease. This idea has been translated into a relatively simple formula. Forces between objects can be co-directed or Read more…
