I-capacitor licandelo lombane elisetyenziselwa ukugcina amandla ombane. Iqulethwe ngamacwecwe amabini okuqhubayo ahlulwe yinto yokukhusela ebizwa ngokuba yi **dielectric**. Xa i-voltage isetyenziswe kwi-capacitor, intsimi yombane yenziwa phakathi kwamacwecwe, evumela ukuba i-capacitor igcine amandla.
Indlela iCapacitor esebenza ngayo
1. Ukutshaja:
Xa i-voltage isetyenziswe kwii-terminals ze-capacitor, intlawulo iqokelela kwiiplate. Enye ipleyiti iqokelela i-positive charge, ngelixa enye iqokelela i-negative charge. Izinto ze-dielectric phakathi kwamacwecwe zithintela intlawulo ukuba ihambe ngokuthe ngqo, igcine amandla kwintsimi yombane eyenziwe. Ukutshaja kuyaqhubeka de i-voltage kwi-capacitor ilingane nombane osetyenzisiweyo.
2. Ukukhupha:
Xa i-capacitor ixhunyiwe kwisiphaluka, intlawulo egciniweyo ibuyela emva kwisiphaluka, idala i-current. Oku kukhulula amandla agciniweyo kumthwalo wesekethe kude kube yilapho umrhumo uphelile.
Iimpawu eziphambili zeeCapacitors
- Ukubanakho:
Ikhono le-capacitor yokugcina intlawulo ibizwa ngokuba yi-capacitance, ilinganiswe kwii-farads (F). Umthamo omkhulu uthetha icapacitorinokugcina imali eninzi. I-capacitance ithonywa ngummandla wendawo yamacwecwe, umgama phakathi kwabo, kunye neempawu ze-dielectric material.
- Ugcino lwamandla:
IiCapacitors zisebenza njengezixhobo zokugcina okwexeshana zamandla ombane, afana neebhetri kodwa ezilungiselelwe ukusetyenziswa kwexesha elifutshane. Baphatha utshintsho olukhawulezayo kumbane kunye nokuguquguquka okugudileyo, okunegalelo ekusebenzeni okuzinzile kwesekethe.
-Ukuvuza kwangoku kunye nokuLinganayo kweSeries Resistance (ESR):
I-Capacitors ifumana ilahleko yamandla ngexesha lokuhlawula kunye nokukhupha imijikelezo. Ukuvuza kwangoku kubhekiselele ekulahlekeni okucothayo kwentlawulo ngokusebenzisa imathiriyeli ye-dielectric nangaphandle komthwalo. I-ESR yinkcaso yangaphakathi ebangelwa zizinto ezingaphakathi kwe-capacitor, ezichaphazela ukusebenza kwayo.
Ukusetyenziswa okuSebenzayo kweeCapacitors
-Uhluzo:
Kwizixhobo zombane, ii-capacitors zisebenza njengezihluzi zokugudisa ukuguquguquka kwamandla ombane kunye nokuphelisa ingxolo engafunekiyo, nokuqinisekisa ukuphuma kwamandla ombane okuzinzileyo.
- Ukudityaniswa kunye nokudibanisa:
Ekugqithiseni umqondiso, ii-capacitors zisetyenziselwa ukudlula iimpawu ze-AC ngelixa zivimbaAmacandelo eDC, ukuthintela ukutshintshwa kwe-DC ekuchaphazela ukusebenza kwesiphaluka.
- Ugcino lwamandla:
IiCapacitors zigcina kwaye zikhulule amandla ngokukhawuleza, zibenza zibe luncedo kwizicelo ezifana nezibane zekhamera, izixhobo zombane, kunye nezinye izixhobo ezifuna ukuqhuma okufutshane kwangoku okuphezulu.
Isishwankathelo
IiCapacitors zidlala indima ebalulekileyo kwiisekethe ze-elektroniki ngokugcina kunye nokukhulula amandla ombane. Banceda ukulawula amandla ombane, ukugcina amandla, kunye nokulawula iimpawu. Ukukhetha uhlobo oluchanekileyo kunye nokucaciswa kwe-capacitor kubalulekile ekuqinisekiseni ukusebenza kunye nokuthembeka kweesekethe ze-elektroniki.
