I isiqondiso zamanje: kusukela lokususa plus futhi okuphambene nalokho?

Sonke siyazi ukuthi ugesi kuyinto ukugeleza iqondiswe izinhlayiya icala by umthelela emkhakheni kagesi. Lokhu uzokutshela yimuphi umfundi. Kodwa umbuzo yini isiqondiso zamanje futhi kwenzekani lalezi zinhlobo efanayo, abaningi bangaba isiqu.

Iphuzu okukhulunywa

Njengoba yaziwa, e umqhubi kagesi idluliselwe electron electrolyte - cations futhi anions (noma nje ion), electron Semiconductors bahlinza okuthiwa "izimbobo", e amagesi - ion futhi electron. Kusukela ukutholakala izinhlayiya aphansi ngendlela impahla enikeziwe conductivity yayo kagesi engaphansi. In the ukungabikho inkambu kagesi kuleli metal umqhubi zamanje ngeke uhambe. Kodwa uma ezingxenyeni zalo ezimbili kuphakama ezingaba umehluko, ngamanye amazwi, voltage ivela ezinyakazayo electron futhi ayeke nezinxushunxushu iza oda bayobizwa wacasulwa lokususa kanye plus kuqonde. Kunengqondo, lokho impendulo yombuzo othi, "Yini i-isiqondiso zamanje?". Kodwa lapho, kwase kulula. Vele ukubheka le encyclopedia noma nje nganoma iyiphi ebhukwinitifundvo physics, like ngokushesha iba kubonakale kuwukuziphikisa. Lithi ibinzana okunemibandela "isiqondiso zamanje" kubonisa isiqondiso ukunyakaza amacala omuhle, ngamanye amazwi, kusuka plus lokususa. Indlela yokubhekana nale sitatimende? Phela, lapha nqunu iso impikiswano eshubile!

Amandla esejwayezi ayenza

Lapho Abantu bafunda ukwenza wesifunda ka DC, babengazi ukuthi mayelana nokuba khona kwamakamu electron. Ikakhulukazi, ngesikhathi asizange usola ukuthi usuka lokususa plus. Lapho amp ahlinzekwa engxenyeni yokuqala yekhulu le-19, indlela yamanje ivela yokuhlanganisa lokususa, zonke wathatha kalula futhi lesi sinqumo kungekho muntu phikisa. Kwathatha iminyaka engu-70, kuze kube yilapho abantu bathola ukuthi le-samanje izinsimbi kungenxa ukuhamba electron. Futhi lapho beqaphela (kwenzeka ngo-1916), bonke ngakho esetshenziswa choice eyenziwe Ampere ukuthi kakade akazange ashintshe lutho.

"I segolide kusho"

I electrolyte omubi icala izinhlayiya ukudlulela cathode futhi omuhle - kuya anode. Kwenzeka okufanayo wamagesi. Uma ucabanga ngalokho isiqondiso wamanje kuleli cala, efikayo engqondweni impendulo eyodwa vo: Hambisa okuguquguqukayo amacala kagesi ngesimiso somshini esivalekile aye komunye nomunye. Uma sithatha lesi sitatimende njengesisekelo, kuzosusa ingxabano ekhona njengamanje. Mhlawumbe kuzobangela ukumangala, kodwa iminyaka namanje ezingaphezu kuka-70 edlule, ososayensi ziye zabhala yokuthi uphawu obuhlukile amacala kagesi e konemimoya conductive ihamba ngempela ngomunye nomunye. Lesi sitatimende kuyiqiniso ngenxa yanoma yisiphi umqhubi is kuye ngohlobo zensimbi, igesi, electrolyte Semiconductor. Kungakhathaliseki ukuthi laliyini, kunethemba ezizoqeda ukuxakeka amagama physics zanamuhla futhi zamukele i definition ocacile walokho ingabe ukuthi isiqondiso esinjalo ukunyakaza zamanje. Umkhuba, yebo, ushintsho kunzima, kodwa udinga ekugcineni konke endaweni yayo.
