Oko kuthethwa yi conductivity

Le conductivity ephawula inkqunto ukuqhuba umbane, eli xabiso na bomzimba ngokomlinganiselo resistivity zombane.

Xa kufikwa apho ixabiso ethile, oko kuthetha ukufumana parameter ukulinganisa unit ebalasele into. Makhe siqale imizekelo elula, eziqhelekileyo eziya kukunceda ngokukhawuleza ukuqonda oko kwenzekayo.

Gravity ngqo - parameter ilula kubonisa mass omnye cubic meter izinto phantsi kweemeko eziqhelekileyo. Kulo mzekelo, i parameter umlinganiselo kilogram, kwaye iyunithi injongosenzi imitha cubic.

Iimeko zemilinganiselo kweyesiqhelo iimeko yokusebenza igalelo ukumisela, njengokuba ukunyuka koxinzelelo, ukuthetha ngokuthe ngqo, i-cubic meter eziphathekayo kuya kuba ubunzima ngaphezu ngamandla eziqhelekileyo. Xa phambili, siphawula ukuba semiconductors, umzekelo, inokuba kulungise kakhulu ukutshintsha zabo nokumelana zombane kunye notshintsho lobushushu okanye illuminance.

Ke kaloku, emva umbuzo wokuba yintoni a conductivity. Njengoko kukhankanyiwe ngasentla, eli xabiso na ukuthengwa resistivity, nto leyo kukuthi ngentetho evakalayo ngolu hlobo lulandelayo:

Le resistivity - izinto kweelana kwi tyhubhu kunye icala imitha 1 yangoku yombane phantsi komqathango wokuba uhamba ngokungqongqo nkqo ukuya kwenye ubuso cube. Ngokufanayo, ungenza aphathe kunye conductivity, kodwa kubalulekile esongeza ukuba iimfuno imilinganiselo phantsi kweemeko eziqhelekileyo kulo mzekelo nazo zibalulekile.

Okwangoku kwezesayensi babekholelwa ukuba conductivity kuba umlinganiselo ngqo isikweri isigxina yamasuntswana, umbane ngoku, imali yabo mbandela yi umthamo kunye nobukhulu kisekiyo ityala yenethiwekhi ukuhamba. Ekuqondeni le ukutyhilwa kukho inkcazo yokuba kutheni umthetho Ohm kaThixo awusebenzi igesi. Xa ixabiso ethile kagesi amandla endle senzeka inkqubo ionization, yaye udaka yangoku liphuma. Oko kusetyenziswa xa ukuwelda okanye sabaqalayo ezibengezelayo.

Ke ukuba izisombululo, kumnandi kakhulu ngakumbi imeko xa siwenza kulo mbono. Le conductivity sezisombululo zixhomekeke kakhulu kwinani abathwali kwentlawulo, ezo ion simahla, kakubi ityala okanye eyakhayo. Ekubeni esulungekileyo amanzi Yek, ion ezinjalo, lo conductivity ezithile amanzi lisondele ku zero. Oku kuthetha ukuba ezikhoyo amanzi acocekileyo akayi kuhamba. Esi simo iindlela ezisekelwe zokulinganisa amanzi anetyuwa okanye ukungcola yamanzi, ingakumbi ph-factor.

Conductivity ke ngoko kubalulekile ukuba eyenza ukusetyenziswa zesinyithi axabisekileyo elektroniki. Ngenxa ixabiso eliphezulu kakhulu kule parameter, izinyithi zobunene kwayimfuneko element izixhobo echanekileyo yokulinganisa. Bambalwa siyazi ukuba reflectivity le but is kwakhona ixhomekeke kakhulu ukuqina kwayo, nto leyo esisizathu sokuba izipili zidla zenziwe ngesiliva.
