Hoci sa kondenz\u00e1tor jednosmern\u00e9ho pr\u00fadu \u010dasto sp\u00e1ja so striedav\u00fdmi obvodmi, m\u00f4\u017ee zohr\u00e1va\u0165 prekvapiv\u00fa a k\u013e\u00fa\u010dov\u00fa \u00falohu aj v obvodoch jednosmern\u00e9ho pr\u00fadu.

Tento pr\u00fad nabije dosky kondenz\u00e1tora a vytvor\u00ed opa\u010dn\u00e9 elektrick\u00e9 pole.<\/li>\n
  • Ust\u00e1len\u00fd stav:<\/strong> Ke\u010f je kondenz\u00e1tor \u00faplne nabit\u00fd, funguje ako otvoren\u00fd obvod, ktor\u00fd blokuje \u010fal\u0161\u00ed tok jednosmern\u00e9ho pr\u00fadu.
