Asho a conductivity

I conductivity ephawula ikhono into ukuqhuba kagesi, lesi silinganiso kuyinto inhlukanozigaba kuya resistivity kagesi.

Uma kuziwa ukubaluleka ethize, kusho ekutholeni ipharamitha ukukala iyunithi libhekene into. Asiqale nge, izibonelo elula ezivamile kuzokusiza ngokushesha baqonde ukuthi kwakwenzekani enkundleni.

Gravity Specific - ipharamitha elula eyabonisa nenqwaba eyodwa imitha cubic of impahla ngaphansi kwezimo ezivamile. Kulokhu, ipharamitha yisikali sokuthi lo kilogram, futhi into iyunithi yilona imitha cubic.

Imibandela yokukala ku evamile izimo zokusebenza okokufaka ukucacisa, njengoba ingcindezi inyuka, empeleni, imitha cubic of material uzoba mass mkhulu kunezinhliziyo ngomfutho evamile. Lapho ubheka ikusasa, siphawula ukuthi Semiconductors, isibonelo, kungenzeka appreciably kakhulu ukushintsha yabo ukumelana kagesi nge kushintsha izinga lokushisa noma illuminance.

Manje emuva umbuzo yini conductivity. Njengoba kushiwo ngenhla, lesi silinganiso iyona okuhambisanayo of resistivity, nakho ngalezi zindlela ezilandelayo:

I resistivity - okokusebenza ukumelana cube nohlangothi lokuzibona 1 imitha kagesi ngaphansi kombandela wokuthi notshwala zamanje ngokuqinile perpendicular omunye ubuso cube. Ngokufanayo, ungakwazi aphathe futhi conductivity, kodwa kuyafaneleka unezela ukuthi izidingo nesilinganiso ngaphansi kwezimo ezivamile ukuze leli cala zibalulekile.

Okwamanje kwezesayensi babekholelwa ukuthi conductivity ngokuqondile wakhona skwele icala kuyizinhlayiyana, ugesi zamanje, lemali yabo indaba ivolumu inhlukanozigaba ukukhokhisa i yenethiwekhi ukuhamba. Esikhathini ukuqonda ngale ncazelo itholakala incazelo yokuthi kungani umthetho Ohm sika asisebenzi amagesi. Ngezinye value ezithile amandla kagesi emkhakheni kwenzeka inqubo ionization, futhi zamanje ngendathane liphuma khona. Lokho isetshenziswa lapho Welding noma aphansi Fluorescent.

Njengoba amakhambi, isimo kuyajabulisa kakhulu uma usondela ke nalo mbono. I conductivity izixazululo ngokuyinhloko ixhomeke ekutheni isibalo kwenkokhiso zenethiwekhi, okuyizinto ion khulula, omubi icala namtjhana abahle. Njengoba okumsulwa amanzi distilled, ion enjalo onawo, conductivity ezithile amanzi eduze zero. Lokhu kusho ukuthi wamanje ngokusebenzisa amanzi ahlanzekile ngeke uhambe. Lesi simo esiyingqayizivele sibangelwa kuyinto izindlela based sokulinganisa usawoti noma ukungcola kwazo zonke izinhlobo amanzi, ikakhulukazi PH-factor.

Conductivity Ngakho kubalulekile ukuthi kwenza ukusetshenziswa lezi zinsimbi eziyigugu, electronics. Ngenxa lenani eliphakeme kakhulu lokhu ipharamitha, izinsimbi yizicukuthwane babe liyisici esidingekayo ka olunembile imishini sokulinganisa. Bambalwa bayazi ukuthi reflectivity we metal kubuye kuncike kakhulu ukumelana layo, yingakho izibuko zivame sasenziwe ngesiliva.
