Uma kuziwa kumabhethri, kubalulekile ukuqonda ukucaciswa kanye nemininingwane yobuchwepheshe ngaphambi kokuthenga.Enye yamapharamitha abalulekile ebhethri amandla ayo amanje, akalwa ngama-amps.Kulesi sihloko, sizoxoxa ngokuthi mangaki ama-amps akubhethri le-9V, okuwuhlobo olujwayelekile lwebhethri elisetshenziswa kumishini eminingi kagesi.Sizophinde sidingide ezinye zezinto ezingathinta ukuphuma kwamanje kwebhethri le-9V.
Iyini i-Ampere?
Okokuqala, masiqonde igama elithi 'ampere'.I-ampere (amp) iyunithi yamanje kagesi ku-International System of Units (SI).Iqanjwe ngesazi sefiziksi esingumFulentshi u-André-Marie Ampère, ikala ukugeleza kwamashaji kagesi ngomqhubi.Ngamagama alula, kufana nezinga lokugeleza kwamanzi ngepayipi.
Liyini Ibhethri le-9V?
Ibhethri le-9V, elivame ukubizwa nge-colloquially ngokuthi 'ibhethri ye-transistor', usayizi ojwayelekile webhethri owethulwa kumarediyo angaphambi kwesikhathi.Inomumo weprism ongunxande onamachopho ayindilinga kanye nesixhumi esisheshayo phezulu.
Lawa mabhethri aziwa ngempilo yawo ende yeshelufu kanye nokuphuma kwamandla okuzinzile kwe-9-volt, okuwenza afaneleke kumadivayisi akhipha amanzi aphansi futhi asetshenziswa ngezikhathi ezithile njengezitholi zentuthu, amawashi, nezilawuli kude.Zibuye zidume ezinhlelweni zokusebenza zomsindo ochwepheshe, njengamamakrofoni angenawaya neziginci zikagesi.
Mangaki ama-Amps akubhethri le-9V?
Manje, enhliziyweni yodaba-mangaki ama-amp akubhethri le-9V?Kubalulekile ukuqaphela ukuthi inani lamanje (ama-amps) elinganikezwa yibhethri alilungisiwe.Kunalokho, kuncike ezintweni ezimbili: umthamo webhethri (akalwa ngamahora angu-milliampere, noma i-mAh) kanye nomthwalo noma ukumelana okusetshenziswa kubhethri (kukalwa ngama-ohms).
Ibhethri le-9V ngokuvamile linomthamo osuka ku-100 kuya ku-600 mAh.Uma sisebenzisa uMthetho ka-Ohm (I = V/R), lapho ngikhona, u-V uyi-voltage, futhi u-R ungukumelana, singabala ukuthi ibhethri elingu-9V ngokwethiyori lingaletha i-current ye-1 Amp (A) uma ukumelana kungu-9. ohms.Kodwa-ke, ngaphansi kwezimo ezisebenzayo, okwamanje langempela lingase libe lincane ngenxa yokumelana kwangaphakathi nezinye izici.
Okukhiphayo kwamanje kwebhethri elingu-9V kungahluka kuye ngohlobo lwebhethri nekhwalithi yebhethri.Kodwa-ke, njengomthetho ojwayelekile, ibhethri elisha le-9V kufanele likwazi ukunikeza amandla amanje acishe abe ngu-500mA (0.5A) isikhathi esifushane.Lokhu okukhiphayo kwamanje kuzokwehla njengoba ibhethri liphuma, futhi kubalulekile ukuqaphela ukuthi ibhethri le-9V lingase lingakwazi ukuhlinzeka okwamanje okwanele kwamanye amadivayisi anamandla amakhulu.
Amandla Amabhethri Ahlukile we-9V
Kunezinhlobo eziningana ezahlukene zamabhethri angu-9V atholakalayo emakethe, ngalinye linezici zalo ezihlukile, amakhono kanye nezicelo.
9V Ibhethri Le-alkaline: Amabhethri e-alkali angu-9V awuhlobo oluvame kakhulu lwebhethri engu-9V futhi atholakala kabanzi ezitolo eziningi.Banikeza amandla amakhulu uma kuqhathaniswa futhi afanele uhla olubanzi lwamadivayisi.Umthamo webhethri ye-alkali engu-9V ungasukela ku-400mAh kuye ku-650mAh.
9V Ibhethri ye-Lithium: Amabhethri e-Lithium 9V aziwa ngokuphila kwawo okude kweshalofu kanye nokuminyana kwamandla aphezulu.Zivame ukusetshenziswa kumadivayisi adonsa amanzi amaningi, njengezitholi zentuthu namakrofoni angenawaya.Umthamo webhethri le-lithium engu-9V ungasukela ku-500mAh kuye ku-1200mAh.
9V Ibhethri ye-NiCad: Amabhethri e-NiCad 9V ayashajwa futhi angasetshenziswa ezinhlelweni ezihlukahlukene, okuhlanganisa amafoni angenazintambo namathoyizi esilawuli kude.Banomthamo ophansi futhi bathambekele kumphumela wenkumbulo.Umthamo webhethri le-9V NiCad ungasukela ku-150mAh kuye ku-300mAh.
9V Ibhethri le-NiMH: Amabhethri e-NiMH 9V nawo ayashajwa futhi anikeza umthamo ophakeme kunamabhethri e-NiCad.Avame ukusetshenziswa kumadivayisi aphathekayo alalelwayo nakwezinye izinhlelo zokusebenza zamandla aphansi ukuya kwamaphakathi.Umthamo webhethri le-9V NiMH ungasukela ku-170mAh kuye ku-300mAh.
9V Ibhethri leZinc-Carbon: Amabhethri e-Zinc-carbon 9V ayinketho eshibhile futhi afaneleka kumadivayisi akhipha amanzi aphansi, njengamawashi nezilawuli kude.Zinomthamo ophansi uma kuqhathaniswa futhi azishajwa kabusha.Umthamo webhethri le-zinc-carbon engu-9V ungasukela ku-200mAh ukuya ku-400mAh.
Kungani Kubalulekile Ukuqonda Ama-Amps?
Ukwazi ama-amps ebhethri kubalulekile ngoba kuthinta ngqo ukusebenza nempilo yedivayisi esebenza ngebhethri.Ibhethri elinesilinganiso se-amp esiphezulu linganika idivayisi amandla isikhathi eside, kanti ibhethri elinesilinganiso se-amp esiphansi kungase kudingeke ukuthi lishintshwe kakhudlwana.
Ukuqonda okwamanje futhi kusiza ekulinganiseni izindleko zokusebenza kanye nembuyiselo yokutshalwa kwezimali kumadivayisi asebenza ngebhethri, okuwukucatshangelwa okubalulekile kokwenziwa kwebhizinisi kuya kwebhizinisi.
Ukukhetha Ibhethri Elilungile
Njengomkhiqizi webhethri ohamba phambili e-China,Amandla we-Weijianginikeza uhla lwamabhethri angu-9V anamakhono ahlukahlukene ukuhlangabezana nezidingo zebhizinisi ezahlukene.Amabhethri ethu adizayinelwe ngezinto ezisezingeni eliphezulu ukuze asebenze kahle nempilo ende, ehlinzeka ngenani elihle kakhulu lebhizinisi lakho.
Uma ukhetha ibhethri, cabangela izidingo zamandla edivayisi nokuthi idinga isikhathi esingakanani ukuthi isebenze phakathi kokushajwa noma ukushintshwa kwebhethri.Futhi, cabangela izimo zokusebenza njengoba amazinga okushisa adlulele angathinta ukusebenza kwebhethri nempilo yokuphila.
Ithimba lethu lochwepheshe lihlale likulungele ukukusiza ekukhetheni ibhethri elifanele izidingo zakho, liqinisekise ukuthi uthola ukusebenza okungcono kakhulu kanye nenani lebhizinisi lakho.
Isiphetho
Sengiphetha, inani lama-amps ebhethri le-9V lincike kumthamo walo kanye nomthwalo osetshenziswa kulo.Njengomnikazi webhizinisi, ukuqonda lo mqondo kungakusiza wenze izinqumo zokuthenga unolwazi futhi uthuthukise ukusebenza kanye nokonga kwezindleko kwamadivayisi akho asebenza ngebhethri.
Xhumana nathi namuhla ukuze uthole ulwazi olwengeziwe ngamabhethri ethu ekhwalithi ephezulu angu-9V futhi usivumele sinikeze ibhizinisi lakho amandla ekuphumeleleni.
