Kodi kugwiritsa ntchito ma LED owonetsa ma capacitor ndi chiyani?Monga wogwiritsa ntchito chiwonetsero cha LED, ndikofunikira kukhala ndi chidziwitso ndi kumvetsetsa kwazinthu zosiyanasiyana zamagetsi.

The LED display capacitor ndi chidebe chomwe chimatha kusunga magetsi.Zimapangidwa ndi mapepala awiri azitsulo omwe ali pafupi, olekanitsidwa ndi zinthu zotetezera.Malinga ndi zida zosiyanasiyana zotetezera, ma capacitor osiyanasiyana amatha kupangidwa.Monga: mica, zadothi, pepala, electrolytic capacitors, etc.

Potengera kapangidwe kake, zowonera zotsogola zimagawidwa kukhala ma capacitor okhazikika ndi ma capacitor osinthika.Capacitor ili ndi kukana kopanda malire kwa DC, ndiko kuti, capacitor ili ndi mphamvu yotchinga ya DC.Kukaniza kwa capacitor kusinthasintha kwapano kumakhudzidwa ndi kuchuluka kwa kusinthasintha kwapano, ndiko kuti, ma capacitor omwe ali ndi mphamvu yofananira amapereka ma capacitive reactances osiyanasiyana ma frequency osiyanasiyana.Nchifukwa chiyani zozizwitsa izi zimachitika?Izi ndichifukwa choti capacitor imadalira pamalipiro ake ndi ntchito yotulutsa kuti igwire ntchito, pomwe chosinthira mphamvu s sichitsekedwa.

Zitsulo ziwiri zazitsulo za LED zowonetsera capacitor ndi zitsulo zina wamba sizimalipidwa.Pamene chosinthira S chatsekedwa, ma electron aulere pa mbale yabwino ya capacitor amakopeka ndi gwero la mphamvu ndikukankhira pa mbale yolakwika.Chifukwa cha zinthu zoteteza pakati pa mbale ziwiri za capacitor, ma elekitironi aulere ochokera ku mbale yabwino amaunjikana pa mbale yoyipa.Mbale yabwino imayimbidwa bwino chifukwa cha kuchepa kwa ma elekitironi, ndipo mbale yolakwika imayimbidwa molakwika chifukwa chakuwonjezeka kwapang'onopang'ono kwa ma electron.

Pali kusiyana komwe kungakhalepo pakati pa mbale ziwiri za LED yowonetsera capacitor.Pamene kusiyana komweku kuli kofanana ndi mphamvu yamagetsi, kulipiritsa kwa capacitor kumayima.Ngati mphamvuyo itadulidwa panthawiyi, capacitor ikhoza kukhalabe ndi magetsi opangira.Kwa capacitor yoyendetsedwa, ngati tilumikiza mbale ziwirizi ndi waya, chifukwa cha kusiyana komwe kulipo pakati pa mbale ziwiri, ma elekitironi adzadutsa muwaya ndikubwerera ku mbale yabwino mpaka kusiyana komwe kungakhalepo pakati pa mbale ziwirizo ndi ziro.

Capacitor yotsogolera imabwezeretsedwa ku dziko losalowerera popanda malipiro, ndipo palibe panopa mu waya.Kuthamanga kwapamwamba kwa magetsi osinthika omwe amagwiritsidwa ntchito pa mbale ziwiri za capacitor kumawonjezera chiwerengero cha kubweza ndi kutulutsa capacitor;Kuthamanga ndi kutulutsa mphamvu kumawonjezekanso;ndiko kunena kuti, kutsekereza kwa capacitor pamlingo wapamwamba kusinthasintha kwakanthawi kumachepetsedwa, ndiko kuti, kuyamwa kwa capacitive kumakhala kochepa, ndipo mosemphanitsa Ma capacitors ali ndi mphamvu yayikulu yotengera kutsika kwapang'onopang'ono.Pakusintha ma frequency omwewo.Kuchuluka kwa chidebecho, kucheperachepera kwa capacitive reactance, ndi kucheperako mphamvu, kumapangitsanso mphamvu ya capacitive.
