Common Anode vs Common Cathode
Anode thiab cathode yog qhov tsim nyog rau kev teeb tsa hluav taws xob qhov twg cov dej ntws tam sim no koom nrog. Electrochemical cells, cathode ray tubes, thiab X-ray raj yog qee qhov piv txwv uas peb tuaj hla anodes thiab cathodes. Thaum ib tug tam sim no ntws, tsis zoo them electrons yog ntws. Hauv lwm lo lus, tam sim no yog nqa los ntawm kev txav electrons. Thaum cov hluav taws xob ntws mus rau ib qho kev taw qhia, peb hais tias tam sim no ntws mus rau qhov sib txawv ntawm cov electrons. Yog li peb tham txog qhov zoo tam sim no. Rau ib lub cuab yeej, thaum peb hais tias 'tam sim no-hauv,' txhais tau hais tias tam sim no ntws mus rau hauv lub kaw lus.'Tam sim no-tawm' txhais tau tias tam sim no ntws tawm ntawm qhov system. Anode thiab cathode yog txhais los ntawm qhov tam sim no ntws. Hauv qee cov khoom siv, peb tsis tuaj yeem hais tias ib qho yog anode thiab lwm yam li cathode. Raws li qhov tshwm sim, ib qho electrode ib zaug ua haujlwm raws li cathode tuaj yeem hloov mus ua haujlwm li anode. Piv txwv li, thaum lub roj teeb rechargeable raug them, lub davhlau ya nyob twg zoo yog lub anode, tab sis thaum tib lub roj teeb tawm, cathode dhau los ua lub davhlau ya nyob twg zoo. Txawm li cas los xij, rau cov roj teeb uas tsis tau them rov qab thiab lub teeb emitting diodes, cov anodes thiab cathodes yog ruaj khov. Txawm li cas los xij, rau lub hom phiaj kev kawm thiab rau peb txoj kev yooj yim, peb tuaj yeem nco qab anode thiab cathode nyob rau hauv kev cuam tshuam rau lawv cov dej num, tsis yog cov qauv.
Common Anode
Anode yog lub davhlau ya nyob twg uas tam sim no ntws-hauv los ntawm sab nraud. Yog hais tias peb coj ib tug electrochemical cell ua piv txwv, anode yuav nco ntsoov raws li lub electrode qhov twg anions nyob rau hauv cov tshuaj electrolytic yog attracted. Yog li los ntawm sab nraud Circuit Court, tam sim no ntws mus rau hauv lub anode, uas txhais tau hais tias cov electrons txav deb ntawm lub anode. Feem ntau, oxidation tshwm sim tshwm sim ntawm qhov anode. Yog li thaum anions tuaj rau hauv lub anode hauv cov tshuaj, lawv raug oxidation thiab tso electrons. Yog li ntawd, muaj electron abundance ntawm lub anode piv rau cathode. Vim li no, electrons ntws mus rau cathode los ntawm anode. Txij li cov dej ntws tam sim no nyob rau hauv qhov sib txawv ntawm cov electron ntws, peb pom nws li tam sim no ntws mus rau hauv anode.
Common anode yog siv nyob rau hauv xya-ntu qhia. Qhov no yog ib qho khoom siv hluav taws xob uas qhia cov lej lej. Lawv tau siv dav hauv cov moos digital thiab ntsuas, thiab lwm yam hauv cov lus qhia no, tag nrho cov anodes txuas nrog rau ib qho taw tes, thiab nws dhau los ua ib qho anode. Yog li ntawd, es tsis txhob xya anodes, tsuas muaj ib qho anode. Fais fab mov qhov kawg zoo yog txuas nrog lub anode. Txawm li cas los xij, lub zog yuav muab rau tag nrho xya ntu.
Common Cathode
Cathode yog cov electrode uas qhov zoo tam sim no ntws tawm ntawm lub cev. Nyob rau hauv ib tug electrochemical cell, nyob rau hauv cov tshuaj, cov cations attracted rau lub cathode. Kev txo qis tshwm sim tshwm sim ntawm lub cathode; yog li ntawd, yuav tsum muaj electrons. Txij li thaum tam sim no ntws tawm ntawm cov electrode, cov electrons tau ntws hauv. Raws li cov electrons no tau siv mus txog qhov kev txo qis, yuav muaj ntau dua electron deficiencies. Qhov no tso cai rau ntau electrons tuaj rau hauv cathode los ntawm anode.
Thaum tag nrho xya cathodes ntawm 7-ntu zaub txuas ua ke, nws dhau los ua cathode. Thaum siv xya ntu, cov cathode feem ntau yuav tsum tau grounded.
Qhov txawv ntawm Common Anode thiab Common Cathode yog dab tsi?
• Hauv xya ntu qhia, thaum tag nrho cov anodes txuas rau ib qho taw tes, nws dhau los ua ib qho anode. Common cathode txhais tau hais tias tag nrho xya cathodes ntawm 7-segment zaub tau txuas ua ke.
• Txhawm rau ua haujlwm, qhov hluav taws xob zoo yuav tsum tau muab rau cov khoom siv anode thiab cov cathode feem ntau yuav tsum tau grounded.
