Abin da irin ƙarfin lantarki

Tare da manufar "ƙarfin lantarki" dukan mu su hadu da kusan a kowace rana, saboda yankin na amfani ne ba iyakance kawai ga kayan aiki. Wannan walƙiya a lokacin ruwan sama, da kuma tartsatsi a kan wani roba tsefe da kuma tufafi na roba zaruruwa da sauransu.

Dry Academic harshen samar da wadannan definition na sabon abu: ƙarfin lantarki - shi ne wani jiki yawa na nuna wani adadin yi ta cajin a 1 C (coulomb) aiki. Wuya, bi da bi, na nuna adadin lura da m conductive abu domin 1 biyu tare da wani halin yanzu na 1 A.

Shi ne ma ya halatta ga wani definition, bisa ga abin da ƙarfin lantarki ne rabo daga aikin yi da lantarki filin a kan motsi na gwajin (da bincike) cajin tsakanin maki biyu, zuwa ga lamba darajar wannan cajin. A wannan yanayin shi ne zaci cewa cajin canja wuri ba zai tasiri a yuwuwar bambancin (ƙarfin lantarki ba ya canja), da kuma hanyar motsi za a iya watsi da. A wani dabara da wannan definition aka rubuta kamar haka:

U = A / q,

inda U - ƙarfin lantarki, A - aiki, q - cajin.

Don tuna da abin da daukar irin ƙarfin lantarki, babu bukatar a koyo, saboda tip ne ko da yaushe a hannu, tun da dukan halin yanzu kafofin nuna irin ƙarfin lantarki darajar da ta girma: shi ne isa zuwa dubi wani baturi. Unit - V (B, V).

The sharuddan "ƙarfin lantarki" domin DC da AC haihuwarka ne daban-daban. A alternating halin yanzu, halin da lokaci-lokaci sinusoid nassi ta hanyar da sifili batu, da ake amfani da lissafi ba instantaneous, kuma RMS darajar. Wannan shi ne yiwu godiya ga cewa ya aiki da mai aiki mikakke kaya yayi dace numerically zuwa DC ƙarfin lantarki.

Wadanda suka samu damar zuwa magance uku-lokaci Motors, haƙĩƙa, kusantar da hankali ga wani bakon shigarwa a cikin fasfo halaye. Akwai, ta hanyar da bugun jini nuna biyu voltages kamar 220/380 V. Babu typo akwai, lalle ne, da kayan aiki ne iya aiki a biyu daban-daban aiki dabi'u. Ina ba da cibiyar sadarwa 380 na iya daukar 220? Sai dai itace, da irin ƙarfin lantarki na iya zama ko dai lokaci ko mikakke, dangane da ji Hanyar. Phase ne m da aunawa da bambanci tsakanin kowane lokaci da kuma tsaka tsaki shugaba, kuma a mikakke - tsakanin zamani conductors. Ta haɗa kaya kewaye a alwatika, wanda zai iya samun wani mikakke kuma daidai lokaci voltages, kuma domin haihuwarka "star" lokaci ne 1,73 sau kasa mikakke.

High ciki juriya ba gabatar da murdiya shunting. Wannan shi ne dalilin da ya sa, misali, a cikin gida da amfani iya zama kai tsaye dangane da wani kanti (sabanin ammeter hada da mai kula da da'ira).

Amma bari storey dabara malamai da kuma bincika, abin da yake da "lantarki ƙarfin lantarki", a cikin sauki mutum harshe. Saboda haka, bambancin da cajin (m) tsakanin biyu sabani maki da shugaba ko lantarki filin. Source da cewa yana sa na motsi da wani shugaba na electrons (da janareta, wani baturi) ya haifar a daya karshen su yawa, da kuma sauran - korau. Haka kuma, da darajar da zargin ne ma daban-daban.
