A conductors a cikin lantarki filin

Daban-daban jiki, kamar yadda ne da aka sani, zuwa kashi nonconductors (dielectrics) da kuma conductors da su lantarki Properties. Daya daga cikin siffofin da da conductors a wani lantarki filin, shi ne cewa zargin ne a ma'auni a kan surface daga gare ta, ciki wanda da lantarki filin ne mãsu fakowa ba. Yadda za a bayyana wannan?

The abu ne cewa, conductors da musamman lantarki zargin. Saboda haka, karafa kamar zargin suna dako kamar electrons da sun rasa lamba tare da kwayoyin halitta. Suna da ake kira free electrons.

Irin wannan electrons a wani shugaba na karfe, an sanya shi a cikin wutar lantarki filayen, a ƙarƙashin rinjayar da karfi filin za ta motsa a cikin wani shugabanci wanda yake daura da lantarki filin daga tsanani.

Kai mai shiryar da ABCD lantarki filin, wanda aka sanya a cikin wani uniform filin, tare da tsanani, daga hagu zuwa dama.

A surface na AC shugaba auku haddi korau cajin, da kuma wuce kima m - zuwa wani DB. A wannan misali mun ga cewa wayoyi a cikin lantarki filin ake wutan lantarki. The zargin cewa ya bayyana a kan surface da shugaba, samar da cikin da shi da wani ƙarin lantarki filin. Its filin Lines da wani gaban shugabanci tare da girmamawa ga Lines na farko filin. A sakamakon haka, da tashin hankali da ƙasa filin a wani shugaba da aka rage, Ina nufin, Yana raunana karfi cewa abubuwa a kan free electrons, da kuma sa su motsi. The zargin cewa suna conductors a wani lantarki filin, da motsi zai daina lokacin da resultant filin ƙarfi a cikin su zama sifili.

Saboda haka, a lokacin da ma'auni na zargin a kan shugaba ciki da filin da ya bace. Its rashi za a iya amfani don kare jiki daga kufan waje lantarki filin. A saboda wannan dalili shi ne ya isa ya kewaya da gawar a bakin ciki conductive Layer, msl, su sanya shi a cikin wani karfe akwatin. Ciki da wannan akwatin da filayen ba zai zama.

Don tabbatar da cewa a wani caji shugaba ne babu lantarki filin, a cikin kwarewa, Faraday gina wani babban waya cages, wanda aka sanya a kan insulators da recharged. Da yake ciki da cell da hypersensitive electroscope, Faraday ya tabbatar da cewa cikin ne ba wani wutar lantarki, ko da yake mayar da hankali a kan m surface ne sosai muhimmanci cajin. Wannan sabon abu ne ake kira da wutar lantarki ta hanyar tasiri ko electrostatic shigar da. Its dalili - sakamako na waje lantarki filin a kan electrons a cikin shugaba unoccupied. Kuma tuhumar da da conductors a wani lantarki filin, da ake kira da jawo zargin.

Ta hanyar rinjayar da wutar lantarki sabon abu ya bayyana janye tsakanin wutan lantarki da kuma nenaelektrizovannymi jikinsu, kazalika da canja wurin da wutar lantarki, da tuhuma da lamba daga jikinsu.

Lokacin da wutan lantarki jiki kusanta ne a wurin sauki shugaba sa'an nan ya bayyana kanta da jawo zargin biyu ãyõyi. Saboda haka, zargin da m alamar za a janyo hankalin zuwa ga jiki, da kuma kamar zargin zai tare. Saboda kamar zargin ne a gefen haske shugaba, da mafi m daga jiki, da resultant na biyu, waɗannan, sojojin ne karfi na janye. Ƙarƙashin rinjayar da wannan karfi ne mai haske shugaba sha'awar jiki. A lokacin lamba na jawo cajin ne na m alamar za a neutralized da inducing cajin bangare wanda yake shi ne daidai da shi a cikin girma. A kan haske shugaba ya kasance iri guda alamar cajin, da kuma jiki.

Saboda gaskiya cewa wani haske shugaba yanzu yana da guda cajin kamar yadda jiki, shi za su tura kashe daga gare shi. abin da muka kiyaye gwaje.

Conductors da dielectrics a cikin lantarki filin da daban-daban Properties. Saboda haka, dielectrics da kusan babu free zargin. Lokacin da sanya shi a cikin wutar lantarki filin daga rabuwa abu ya faru.
