Electric halin yanzu a cikin daban-daban kafofin watsa labarai

Daya daga cikin mafi muhimmanci ma'anar kimiyyar lissafi ya furta cewa, da lantarki - shi ne wani umurni da motsi na barbashi da ciwon wani cajin. Daga wannan za mu iya cewa domin cewa lantarki halin yanzu ya bayyana, da shi wajibi ne, a gaban karfe, ruwa ko kuma wani abu daga cikin free electrons ko ions, wanda za ta motsa a ƙarƙashin rinjayar da electromagnetic filin. A lokaci guda, da wutar lantarki yanzu a cikin daban-daban kafofin watsa labarai za su mallaki wasu halaye, saboda wanda da ya kwarara a cikin kowane daga cikinsu zai zama daban-daban.

Idan muka yi la'akari da fasali na samuwar da ya kwarara daga lantarki a karafa, da farko na dukkan kula zuwa karfe tsarin da kanta, wanda yake shi ne crystal raga. A cikin nodes na raga ana shirya ions da kyau cajin, kuma a cikin sarari tsakanin nodes a wani bazuwar domin motsi electrons da wani mummunan cajin. Idan da karfe don ƙirƙirar a kusa da lantarki filin, da electron motsi so tsanake. Yana iya ƙarasa da cewa, tare da girmamawa ga karafa da lantarki - mai directional motsi electrons ne.

Babban halayyar da ya kwarara daga lantarki a karafa ne a halin yanzu-ƙarfin lantarki magana ne da aka sani a matsayin Ohm ta dokar. A cewar wannan doka, a halin yanzu shi ne kai tsaye dogara a kan irin ƙarfin lantarki da kuma inversely na gwargwado ga juriya. Nazarin da lantarki a da dama muhallin, shi wajibi ne don biya musamman da hankali ga ta samuwar da yayyo a cikin wani ruwa matsakaici.

Electric halin yanzu a Wutan auku saboda da dauki, aka sani electrolytic dissociation. Its ainihi kunshi a cikin Lalacewar kwayoyin na alkalis, acid salts ko a cikin tabbatacce kuma korau ions, wanda suke dako na wutar lantarki a taya. The abu ne cewa, a lokacin da bayani ya fara aiki da electromagnetic filin, da m motsi na ions ne tuba zuwa cikin wani umurni. A wannan yanayin, tabbatacce ions fara motsawa zuwa ga lantarki da ciwon wani mummunan cajin, kuma korau - to da ciwon tabbatacce cajin. Saboda haka, da bambanci ga wannan karfe, da wutar lantarki yanzu a cikin electrolyte ne wani umurni da motsi na da ions. Bugu da ƙari kuma, shi ne ya kamata a lura da cewa a lokacin da nassi daga wadannan ions ta hanyar da mafita ga ko da yaushe wayoyin suna kafa na abubuwa da suke da tsarin da aka gyara daga cikin bayani, ko yana da wani Alkali, wani acid ko gishiri daga gare ta. Wannan sabon abu, da ake kira electrolysis, an yi amfani da ko'ina a cikin masana'antu da shuke-shuke, don samar da m karafa, kazalika for shafi da kuma polishing na daban-daban kayayyakin.

Idan akai la'akari da lantarki halin yanzu a cikin daban-daban yanayin, musamman a karafa a taya, muna nuna cewa wadannan abubuwa suna riga free ions ko electrons. Kuma abin da ya faru da gas, wanda aka sani da za a hada da tsaka tsaki kwayoyin? Electric halin yanzu ba tare da free barbashi tare da wani korau ko tabbatacce cajin zai yiwu, don haka ya fara da gas dole ne ionized, Ina nufin haifar da cajin barbashi a cikinta. Ciyar da wannan makamashi zai zama ionization makamashi, wanda ya kai matsakaicin dabi'u a cikin inert gas, da kuma m - sunadaran Alkali karafa. Ionization na gas sakamakon a cewa shi ne kafa a uku daban-daban iri iri na cajin barbashi - electrons da ciwon wani mummunan cajin, kazalika da kyau da kuma mummunan ions. Duk wadannan barbashi ƙarƙashin rinjayar wani waje filin fara matsawa a wani tsanake, wadannan guda manufa matsayin cewa daga cikin motsi na ions a taya. Saboda haka, lantarki halin yanzu a cikin gas ne directed motsi a matsayin ions (tabbatacce kuma korau), kuma electrons.

Kammala, shi ne zai yiwu a lura da wadannan: an wutar lantarki a daban-daban kafofin watsa labarai yana da halaye, wanda ake amfani da ko'ina a daban-daban duniyoyin na kasa da tattalin arziki, da ma a gudanar da bincike gwaje-gwajen.
