Electric charge: an evolving concept ... More than 2,000 years have passed until, in the mid-sixteenth century the study of the phenomena observed by Tales return then to be focused more closely, and technical conditions much higher. The English physician William Gilbert(1540-1603), Figure (2), resumed the experiments and found that other types of materials also showed behavior similar to amber, that is, when rubbed between them, these materials passed to attract others, compose -ing up like amber. When performing experience friction with other materials besides amber, Gilbert realized that after the friction could happen beyond attraction, repulsion also. Then proposed that these materials emitted a telogen, which was responsible for the phenomenon. Just as the atmosphere was effluvium that pulled the bodies to the earth, the atmosphere was electric effluvium responsible for the electric force exerted on light bodies. Another contribution came from Otto von Guericke(1602-1686), mayor of Magdeburg, but also interested in the science. Guericke developed the Electrostatic first machines, such as that illustrated in Figure (3), which consisted of spheres composed of fused mineral, which he believed to be the composition of the earth. These spheres were set around an axis could rotate. Guericke found that rubbing the ball with his hand to his gi-ra-la, it acquired ownership of attraction and sparks eliminated.

Električni naboj: razvija koncept ... Više od 2.000 godina je prošlo dok se, u sredinom šesnaestog stoljeća proučavanje fenomena koje se pridržavaju Priče vrate onda bi se više usredotočila usko, i tehnički uvjeti znatno veći. Englezi liječnik William Gilbert(1540-1603), slika (2), nastavio eksperimente i otkrili da su druge vrste materijala također je pokazala slično ponašanje jantara, koji je, kad je protrlja između njih, ti materijali prošli privući druge, sastaviti -ing kao Amber. Prilikom obavljanja iskustvo trenje s drugim materijalima osim jantara, Gilbert je shvatio da nakon trenje može dogoditi izvan privlačnost, odbojnost također. Zatim je predložio da se ti materijali emitiraju telogenu koji je odgovoran za pojavu. Baš kao što je atmosfera bila effluvium da je povukao tijela na zemlju, atmosfera je bila električna effluvium odgovoran za električne sile koje djeluje na svjetlosnim tijelima. Još jedan doprinos došao od Otta von Guericke(1602-1686), gradonačelnik Magdeburga, ali i zainteresirani u znanosti. Guericke razvijena Elektrostatički prvi strojevi, kao što su to prikazano na slici (3), koja se sastojala od sfera sastoji od lijevanog minerala, koji je vjerovao da se sastav Zemlje. Te sfere su postavili oko osi mogla okretati. Guericke otkrio da trljanjem loptu rukom u svomgi-RA-la, što je stekla vlasništvo nad privlačnosti i iskre eliminirani.
