can electric charge exist in the absence of a charged particle?
... Up until the 1820’s the only magnets that were known were lodestones and magnets made of iron such as compass needles. Then in 1820 Hans Christian Oersted was conducting a demonstration of the heating of a wire by means of an electric current. Coincidentally he also planned a demonstration of the ef ...

... In the insulating region of a capacitor, there is a small number of free electrons due to impurities and other defects. These electrons are accelerated by the electric field and collide with the lattice structure. If the field strength is high enough, the electron generates more electrons with colli ...
