Mene ne sinusoidal yanzu

Da hujjar cewa sinusoidal alternating halin yanzu gudana a cikin conductors na iyali wayoyi, ji kome. Amma ga wani mutum wanda ba a sani da lantarki injiniya, da sharuddan "ba tare da" da kuma, musamman, "m", kome aka ce. A cikin wannan takarda, mun yi kokarin ba da wani janar ra'ayin shi, da sauki fahimta ga kowa da kowa.

Da farko, kana bukatar ka ƙayyade domin cewa irin wannan lantarki a halin yanzu. Bisa ga m bayani na yanzu - directed motsi na na farko barbashi da ciwon lura tabbatacce ko korau alama. Yawancin lokaci, da barbashi na electrons fahimta, amma wannan ba gaskiya ba ne. Atom cewa ya rasa electrons saboda protons ba a cikin nucleus din yakan mallaki wani m cajin, zama ion. EMF rinjayar ba kawai electron amma kuma ga shi. Isar da shi a tuna da cewa, a cikin lissafin ga m shugabanci na yanzu motsi samu daga da su debe, ko da yake a gaskiya, da barnatar da cajin barbashi motsa a gaban shugabanci.

Ina wadannan barbashi? Wakiltar shugaba tsarin: crystal raga tare da kwayoyin halitta a cikin nodes. Kowane zarra za a iya wajen bayyana a matsayin mai dada hasken rana tsarin. A tsakiyar wani m core kunshi protons da neutrons, da kuma electrons motsa a falakinsu a kusa da shi.

Jami'in na proton ne tabbatacce kuma korau electrons, saboda haka suna da tarayyar janyo hankalin. A kusa da tsakiya, da karfi da hulda. Don yanzu taso daga bukatar free sunadaran electrons da kuma sa su motsa a cikin so shugabanci. A janareto wannan aiki nasarar da za'ayi da wani juyawa Magnetic filin. An ruwaito samarwar makamashi electrons a cikin matsanancin falakinsu, sakewa da su. Hakika, babu wani kai tsaye zirga-zirga. Yana da wani musayar wadannan barbashi tsakanin mafi kusa kwayoyin halitta.

Inda ya aikata da sunan "sinusoidal halin yanzu"? Dalilin wannan samar da hanya. Mun wakiltar biyu daura da sandunan na maganadisu, da kuma tsakanin Lines na filin ƙarfi. Mun sanya frame da shugaba a cikin wannan filin. Its iyakar an haɗa wani kaya, kafa wani madauki (kewaye). Juyawa bezel. A daidai lokacin da aka located a layi daya zuwa saman na maganadisu, babu halin yanzu, domin kuwa babu mahada tare da Lines na tashin hankali (garesu daga cikin firam ne ja ruwa). Ga shi ne dan kadan juya, da Lines na Magnetic filin haye shugaba, saki electrons da kuma yanzu haka ta taso.

A daidai wannan lokaci da wancan gefe na firam da traverses da filin, amma a kan kishiyar sashi. Matsakaicin darajar halin yanzu - da a tsaye jeri. Sinusoidal halin yanzu - shi ne mai zana wakilci na wannan tsari. Ba tare da shi da wuya a gane da aiki na lantarki kayan. Jadawali nuna sinusoidal halin yanzu wakiltar Cartesian kula a cikin jirgin sama. A tsaye halin yanzu axis an jinkirta, kuma a kwance - lokaci. Saboda a lokacin da juyawa frame rubuce dabi'u suna daga lokaci zuwa lokaci maimaita, aka generated sinusoidal halin yanzu sãɓãwar launukansa a shugabanci da kuma girma. Strung kamar ba tare da kalaman a kan lokaci axis, tun da kashi located sama da axis of kalaman (tabbatacce alamar), da kuma ƙananan part (korau). Tsororuwar cikin tãguwar ruwa dace da matsayin da firam layi daya da Lines daga cikin filin tsanani, da kuma mahada na lokaci axis (na yanzu shi ne sifili) - perpendicular.

Banana kewaye sinusoidal halin yanzu mafi yadu, kamar yadda irin wannan ikon sosai kawai tuba da gidajen wuta da sauran lantarki kewaye abubuwa, kyale watsa kan manyan nisa, da kuma bukata daidaitowa. Bayan haka, tsara manufa da shi ya shafi halittar wani sinusoidal halin yanzu.
