Le anode kunye cathode - yintoni na nokuqaphela njani?

Malunga anode kunye cathode of umbane kufuneka ukwazi abo benza elektroniki pfunaka. Ntoni kwaye sibizwa njani? Kutheni kunjalo? Iya kuba olunzulu ingqwalasela yesihloko ukusuka kwindawo Ngenxa radio engahlawulwayo kuphela, kodwa chemistry. Nhlamuselo kakhulu ethandwayo ngolu hlobo lulandelayo: anode - i electrode HIV, kwaye cathode - negative. Awu, oku akusoloko kunjalo kwaye zingagqibeki. Ukuze ukwazi ukuchaza anode kunye cathode, kuyimfuneko ukuba kubekho isiseko ithiyori kwaye siyazi ukuba abe nguewe. Makhe sihlolisise le Article.

anode

Ethetha GOST 15596-82, nto leyo ukwenza kwemichiza imithombo yangoku. Thina abanomdla inkcazelo ibekwe kwiphepha wesithathu. Ngokutsho GOST, i electrode esibi iseli electrochemical nto kanye anode. Oko kunjalo, ewe! Yaye kutheni kunjalo? Inyaniso kukuba ngawo lo umbane ophuma wesekethe angaphandle kumthombo ngokwayo. Njengoko ubona, akukho lula njengoko kubonakala xa efika kuqala. Kusenokuba kucetyiswa ukuba siqwalasele ngenyameko lo mfanekiso kweli nqaku, ukuba umxholo ubonakala unzima kakhulu - aya kukunceda ukuba uqonde into umbhali afuna ukusibonisa kuwe.

cathode

Kuchatshazelwe zonke ukuya GOST efanayo 15596-82. I electrode esihle yeseli electrochemical kukuba, xa ukubhobhoza kwayo kusa- bajikeleze lwangaphandle kuzo. Njengoko ubona, i-data eziqulathwe IEC 15596-82, ukujonga imeko ukusuka kwindawo ezahlukeneyo. Ngoko ke, ngokubonisana nabanye malunga izakhiwo ezithile kufuneka ize nizilumkele ke kunene.

Livela amagama

Bafaka ngaphezulu Faraday ngoJanuwari 1834, ukuthintela ukubhideka kunye ukuphumeza ukuchana enkulu. Yena wanikela inguqulo yakhe, nokukhumbula umzekelo kwelanga. Ngoko, xa efumana anode - liyenyuka. Sun ihamba phezulu (current ongena). Cathode - ihleliwe. Ilanga (current in).

iityhubhu UMZEKELO radio and diode

Siyaqhubeka baqonde ukuba ebhekisela koko kusetyenziswa. Masithi omnye amandla sinazo ezi abathengi kwimeko evulekileyo (in live). Ngoko ke, ukususela wesekethe lwangaphandle yi diode ilungu anode yi ombane. Kodwa ke musa ukuba badidekile ngenxa yale ingcaciso evela ngakwicala electron. Esebenzisa cathode ezihamba nesekethe lwangaphandle zokuphuma element yangoku zombane babesebenzisa. Imeko liqulunqe namhlanje, ukhumbuza iimeko xa abantu bajonge indlela zocaphulo. Ukuba idatha zibhekisela complex - khumbula ukuba ukuqonda kule ndlela ngokuyimfuneko kuphela ukuba ekhemisi. Kwaye ngoku ke masenze ukufakwa umva. Kusenokwenzeka ukuba kuqatshelwe ukuba ilight semiconductor ngokubonakalayo akayi ukuqhuba yangoku. Le Ngaphandle kuphela apha - izinto hlula umva. A diode lwepolitiki (kenotron, unomathotholo) uya jikelele baziphathe yangoku umva. Ngoko ke ingqalelo (ngokuqgibeleleyo) ukuba akathanga ukuya kuwo. Ngoko ke, izigqibo formal kule anode diode kunye cathode musa ukwenza imisebenzi yazo.

Kutheni kukho isiphithiphithi?

Ngokukhethekileyo, ukuze kube lula ukufunda kunye nesicelo esebenzayo, kwagqitywa ukuba izinto igama ezinjengeetheminali diode akayi kutshintsha kungakhathaliseki uhlobo yakho uqhagamshelwano, kwaye baya "iqhotyoshelwe 'ukuba iziphumo ezibonakalayo. Kodwa oku akusebenzi neebhetri. Ngoko, kwi ilight semiconductor yonke kuxhomekeke kuhlobo conductivity yikristale. Kwimibhobho emoyeni lo mbuzo lubotshelelwe i electrode nekhupha electron endaweni welungiselelo ntambo. Kakade ke, apha kukho ezinye bokuqonda, umzekelo, ngokusebenzisa loo izixhobo semiconductor, njengokuba suppressor kunye diode zener inokuba kancinane reverse flow lwangoku, kodwa apha kukho ezichaphazela, ngokucacileyo ngaphaya kwemida yeli nqaku.

Uphando nge accumulator yombane

Oku ngokwenene umzekelo classic komthombo chemical umbane, elivuselelwa. Ibhetri kwenye iintlobo ezimbini: isigxina / nokukhutshwa. Kuzo zombini ezi meko ziya kuba indlela ezahlukeneyo yangoku yombane. Kodwa qaphela ukuba ezichaseneyo kwe i electrode ngexesha elifanayo akayi kutshintsha. Kwaye enze iindima ezahlukeneyo:

1. Ngeli ezibiza, i electrode omhle uyasamkela umbane kunye anode, kwaye ezingentle kunye oyiyekayo ebizwa cathode.
2. Xa kungekho bentshukumo phezu kwawo ukuba aqhube incoko akwenzi ngqiqo.
3. Ngexesha lampompoza electrode ezintle ukhupha umsinga wombane kunye cathode, kwaye elibi ifumana kwaye kuthiwa anode.

On Electrochemistry Isho Word

Isebenzisa nkcazelo eyahlukileyo kancinane. Ngoko ke, lo anode ithathwa njengento electrode apho kuthi iinkqubo igcwala. Kwaye zifundo rkukhunjulwe chemistry, unako ukuphendula kwenzeka ntoni kwelinye icala? I welding apho iinkqubo wayelikhoboka, ebizwa ngokuba cathode. Kodwa akukho Ngokubhekiselele kwizixhobo ze-elektroniki. Makhe sijonge ixabiso reactions igcwala-ukuncitshiswa kuthi:

1. Igcwala. Kukho inkqubo ukubuya i yamasuntswana electron. Cala iba kwaku- entle, kwaye ezigxekayo namandla.
2. Recovery. Inkqubo zokufumana yamasuntswana electron. Positive similise kwaku- cala, uze emva koko elibi kwi eziphindaphindayo.
3. Ezi nkqubo zimbini lixhomekeke kwelinye (umzekelo, inani elektroni yona ilingana adjoint inani lazo).

Faraday kwakhona ukubonisa amagama ziye zaziswa ukuba izinto athathe inxaxheba ekudibaneni kwemichiza:

1. Kubeke. Ngoko wabiza elihle ityala ion ukuba lihamba isicombululo electrolyte ukuya esibondeni okubi (cathode).
2. Anions. Ngoko ke abizwa ngokuba ezimbi lihamba isisombululo electrolyte ngaphakathi kwipali entle (anode).

Indlela abasabela yamachiza zenzeke?

Igcwala nokunciphisa isiqingatha-reactions abazakluleyo emajukujukwini. Incedisa elektroni phakathi cathode kunye anode wenziwa ngokungqalileyo, kodwa ngumbhexeshi yesekethe lwangaphandle, nto leyo idala umsinga wombane. Apha uyakwazi singabonakala interconversion kwiimo yemichiza lombane amandla. Ngoko ke, ukuba zenze inkqubo yesekethe yangaphandle izinikezeli eendidi ezahlukeneyo (oko kukuthi yintoni i electrode kwi electrolyte), kwaye kuyimfuneko ukuba usebenzise metal. Yabona, le ombane phakathi anode kunye cathode ikhona njenge caveat. Kwaye ukuba akukho nto leyo ethintela ngqo ukwenza inkqubo kuyimfuneko, ixabiso le mithombo yemichiza ngoku bekuya kuba sezantsi kakhulu. Ngoko ke, ngenxa yokuba yoyalo kuyimfuneko ukuhamba phezu scheme, ziqokelelwe kwaye wasebenza njengoko uchwepheshe.

Yintoni na: Inyathelo 1

Ngoku makhe ukumisela ukuba ngowuphi zona. Thatha galvanic cell-Jacobi Daniel. Kwelinye icala elinye le nkqubo ibandakanya i electrode zinc, nto leyo egxile kumxube zinc sulfate. Ngoko kukho umqobo amazwe. Yaye kwelinye icala sele electrode sobhedu leyo ilahlwe kwindawo isisombululo of sulfate yobhedu. Zihlanganiswe kunye namanye, kodwa iimpawu yemichiza ekudibaneni asityhafi ihlangane.

Inyathelo 2: Inkqubo

Izinki igcwala kwenzeka kwaye electron ukuhamba ngapha isekethe angaphandle zezobhedu. Ngoko kwenzeka ukuba iseli electrochemical une anode, kakubi ityala, kwaye cathode - ezakhayo. Ngaphezu koko, le nkqubo kwenzeka kuphela kwiimeko apho electron kulapho ukuba "ukuhamba". Inyaniso kukuba ukufumana ukusuka electrode ngqo omnye kuthintela ubukho "yodwa."

Inyathelo 3: Electrolysis

Makhe sijonge inkqubo electrolysis. Ukufakelwa ukuze ndiye yayo inqanawa apho kukho isisombululo electrolyte okanye ndininyibilikise. I electrode sele ezimbini isusiwe. Bona eqhagamshelwe umthombo wamandla DC. Le anode kulo mzekelo - i electrode edityaniswe kwi esibondeni ezintle. Nantsi into oxidized. A electrode kakubi ebizwayo - le cathode na. Apha, yokusabela unciphiso kuthatha indawo.

Inyathelo 4: Ekugqibeleni

Ngoko ke, xa usebenzisa la magama kufuneka kusoloko kukhunjulwa ukuba anode ayikho 100% yamatyala osetyenziswayo ukubonisa i electrode elibi. Kwakhona, lo cathode unakho nqapha ingazehlela zabo ezintle. Konke kuxhomekeke uhlobo nkqubo ithatha indawo kwi electrode: a ekunciphiseni okanye oxidizing.

isiphelo

Kuko konke oku - akukho nzima kakhulu, kodwa oko akunakuthethwa ukuba ezilula. Siye sahlolisisa iseli galvanic, le anode kunye cathode ngokubhekiselele icebo, ngoku iingxaki kunye uqhagamshelwano unikezelo lwamandla ixesha yokusebenza kufuneka ungabi. Kwaye ekugqibeleni, kufuneka ukuba ushiye exabiseke kakhulu kancinci ulwazi kuwe. Soloko engqondweni umahluko, eba eyenziwa cathode / isakhono le anode. Into yokuba ukuthanda wokuqala kuhlala bit enkulu. Oku kubangelwa yinto yokuba ukusebenza ayisebenzi nomfuziselo ka-100% yaye inxalenye yoyalo dissipated. Kungenxa yale ungabona ukuba iibhetri wakhe wawunomda kwinani amaxesha unecala nokudubula.
