 Prvn\u00ed doopravdy vytvo\u0159en\u00fd proud byl elektrochemickou cestou. Nejsp\u00ed\u0161 jste ji\u017e n\u011bkdy sly\u0161eli pojem \u201eVolt\u016fv \u010dl\u00e1nek\u201c. Mezi r\u016fzn\u00fdmi kovy vznik\u00e1 rozd\u00edln\u00e9 nap\u011bt\u00ed. Nejlep\u0161\u00ed kombinace dos\u00e1hneme pomoc\u00ed zinku a m\u011bdi (Zinkum, Cuprum). Pokud je\u0161t\u011b tento \u010dl\u00e1nek pos\u00edl\u00edme o z\u00e1sadu \u010di kyselinu, vznikne, konkr\u00e9tn\u011b kyselinu s\u00edrovou (H2SO4), dostaneme nap\u011bt\u00ed 1 V (Volt) Skl\u00e1d\u00e1n\u00edm t\u011bchto \u010dl\u00e1nk\u016f pak m\u016f\u017eeme dos\u00e1hnout rozd\u00edln\u00e9ho nap\u011bt\u00ed, \u010di proudu.
 V dne\u0161n\u00ed dob\u011b je nejv\u00edce pou\u017e\u00edvan\u00fd proud nikoli stejnosm\u011brn\u00fd, ale st\u0159\u00eddav\u00fd. St\u0159\u00eddav\u00fd proud vznik\u00e1 pomoc\u00ed takzvan\u00e9 elektromagnetick\u00e9 indukce. Jedn\u00e1 se o energii, kter\u00e1 vznik\u00e1 ot\u00e1\u010den\u00edm magnetu v sou\u010d\u00e1stce, kter\u00e1 se naz\u00fdv\u00e1 c\u00edvka. Jedn\u00e1 se v podstat\u011b o navinut\u00fd dr\u00e1t. Zm\u011bnou magnetick\u00e9ho pole c\u00edvky se v n\u00ed generuje proud, Pokud magnetem pouze ot\u00e1\u010d\u00edme, st\u0159\u00edd\u00e1 se i sm\u011br proudu a proto tedy \u201est\u0159\u00eddav\u00fd\u201c.

Ve v\u0161ech je ve v\u00fdsledku pouze turb\u00edna, kter\u00e1 rozt\u00e1\u010d\u00ed velik\u00fd magnet. Nejedn\u00e1 se o nic slo\u017eit\u00e9ho.
 Pokud budete cht\u00edt vytvo\u0159it proud, m\u00e1te hned n\u011bkolik mo\u017enost\u00ed.
