Ama-resistors anamandla aphezulu yisisombululo esiphezulu sokugcina amandla.
Asetshenziswa kukho konke kusukela kumathuluzi aselabhorethri kuya ezintweni ezithengiswayo.
Manje sezijwayeleke kakhulu ezindaweni zokuhlala nezamabhizinisi amancane ngenxa yokusebenza kahle kwazo kwamandla, ukonga kwezindleko, kanye nedizayini elula.
Isibonelo, isivimbeli samandla aphezulu singasetshenziswa njengesipele sebhethri sesistimu yakho yokuphepha yasekhaya noma njengesiphakeli samandla sekhompyutha engakwazi ukufinyelela kugesi.
I-resistor enamandla amakhulu iyingxenye ye-elekthronikhi egcina amandla kagesi ngokuwaguqulela ekushiseni kunokuba abe namandla amakhemikhali.
Uma amandla eseshintshiwe abe ukushisa, ngeke aphinde aguqulwe abe amandla kagesi futhi.
Uma ubona i-resistor yamandla aphezulu (ebuye ibizwe ngokuthi i-varistor), empeleni ubona esinye sezici zayo: ukukhishwa kwamandla kagesi akhuphukayo ngamavelu okumelana aphezulu kunalokho okuvame ukutholakala kwenye indawo.
Isibonelo, uma usebenzisa isibani se-incandescent ekukhanyeni okugcwele, idonsa ama-watts angu-60 kagesi kusokhethi odongeni.
Isibani esijwayelekile se-incandescent sinama-volts angu-12 kuphela agijima kuso; ngakho-ke, idinga amandla angaphansi kwe-watt engu-1 ukuze isebenze ekukhanyeni okugcwele ngama-watts angama-60 agcinwe ngaphakathi kwesibani.
I-resistor enamandla amakhulu enenani lokumelana elifanayo nelabhu lokukhanyisa i-incandescent ikhiqiza amandla kagesi aphindwe cishe izikhathi ezingu-90 kunalokho okudingekayo ekukhanyeni okugcwele ngamavolthi angu-12 kuphela agijima kuyo - futhi lokhu kubangela umthamo omkhulu wokugcina ugesi ngaphandle kokudinga ugesi owengeziwe ogelezayo. ngayo… okusho okuncane
Iyini i-High-Energy Resistor?
Izihluthulelo zamandla aphezulu ziyizingxenye ze-elekthronikhi eziguqula ugesi ube ukushisa.
Izinto ezivimbela amandla aphezulu zingasetshenziswa ukugcina ugesi.
Uma uxhuma izinto zikagesi odongeni, isibonelo, amandla kagesi aphuma kusokhethi odongeni angaba ngu-110 volts.
Uma uxhuma i-resistor yamandla aphezulu esokhethi esodongeni, i-voltage yehla ifike cishe ku-12 volts.
Lokhu kungenxa yokuthi uma uxhuma i-resistor esokhethi yodonga, amandla adlula esiphikisayo esikhundleni salokho.
Lapho okokusebenza kuxhunywe ku-resistor, okwamanje kuncishiswa ngenani elifanayo nelokwehliswa kwe-voltage.
Izinqamuleli zamandla aphezulu nazo zisetshenziswa emishinini yokonga amandla njengamalambu okukhanya akonga amandla, izifudumezi, nama-air conditioner.
Lawa madivayisi anenzwa ethola inani lamandla asetshenziswayo.
Uma inani lamandla asetshenziswayo lingaphansi kwenani lamandla agcinwe kusiphikisa samandla aphezulu, inzwa ivala umthombo wamandla ukuze kungabe kusasetshenziswa ugesi.
Lokhu kusiza ekongeni amandla.
Sisebenza Kanjani I-High-Energy Resistor?
Izinqamuleli ezinamandla aphezulu ziklanyelwe ukusebenza ngamavelu athile okumelana ngaphezu kwamandla kagesi ajwayelekile noma amanje ahlinzekwa yintambo yamandla.
Isibonelo, ake sithi unomthombo wamandla angu-12-volt ophuma endaweni ephuma odongeni.
Kule voltage, ungasebenzisa kalula izinto eziningi ezixhunywe odongeni nge-watt engu-1 kuphela yamandla.
Kodwa ake sithi ubufuna ukusebenzisa isibani se-incandescent ngomthombo ofanayo wamandla angu-12-volt.
Kumandla angu-1 watt, isibani sizokhanya ngokufiphele.
I-resistor enamandla amakhulu esinokumelana okuthile singasetshenziswa ukusebenzisa isibani ngokukhanya okugcwele ngamawathi angu-12 wamandla.
Manje ake sithi unekhompyutha engenawo ugesi otholakalayo.
A high-energy resistor ingasetshenziswa ukusebenzisa ikhompyutha ngamandla angu-12 watts.
Lokhu kuwusizo ikakhulukazi ezindaweni zasemaphandleni, lapho kungase kube khona ukufinyelela okuncane noma kungabi khona nhlobo emithonjeni yamandla ngaphandle kwamabhethri emoto.
Izinhlobo zama-High-Energy Resistors
I-Varistor: I-varistor iwuhlobo lwe-low-voltage, olumelana kakhulu nokumelana namandla aphezulu.

- Ukudluliswa kwedatha: Amadivayisi anamandla amakhulu angasetshenziswa ukudlulisa idatha ngaphandle kokusebenzisa irutha, imodemu, noma ezinye izindlela ze ukudluliswa kwedatha.
Amadivayisi anamandla aphansi angahlala kuhabhu kunethiwekhi futhi anikeze ukufinyelela kwe-inthanethi kumakhompyutha ngaphandle kokusebenzisa umzila.
– Amandla ekhompyutha: Ikhompyutha engakwazi ukungena emshinini kagesi inganikwa amandla ngokumelana namandla amakhulu.
Imishini enamandla aphansi ingasetshenziswa ukunika amandla omakhalekhukhwini nezinye izinto zikagesi ezincane.
Amadivayisi anamandla aphezulu anganika amandla amakhompyutha nezinye izinto zikagesi ezisindayo ngaphandle kokukhipha ibhethri.
Ungakhetha kanjani i-resistor ephezulu yamandla?
Izinto ezivimbela amandla aphezulu zintsha ezimakethe zokuhlala kanye nezamabhizinisi amancane.
Ngenxa yalokho, zingabiza kakhulu kunezinqamuleli ezijwayelekile.
Ukuze ukhethe i-resistor yamandla aphezulu efanele, udinga ukuqonda ubukhulu be-voltage namandla amanje idivayisi engakwazi ukuyiphatha ngokuphepha.
Ishadi elingezansi lizokusiza uqonde amandla kagesi kanye nezilinganiso zamanje zamadivayisi anamandla amakhulu.
Lapho ukhetha i-resistor ephezulu yamandla, udinga futhi ukukhumbula umthombo wamandla.
Amadivayisi anamandla aphansi anganikwa amandla ngamabhethri noma izindawo zodonga.
Amadivayisi anamandla aphezulu njengama-microwave noma ama-drill anganikwa amandla ngamadivayisi anamandla aphansi.
Khumbula ukuthi amadivayisi anamandla amakhulu aklanyelwe ukuphatha inani elithile lamandla.
Uma ufuna ukusebenzisa idivayisi enamandla amakhulu, uzodinga ukuthola isivimbeli samandla aphezulu esinamandla aphansi.
