Mene ne electromotive karfi

A wannan labarin, za mu magana game da abin da yake cikin electromotive karfi ikon tushen da kuma abin da yake da dangantaka da wasu sigogi na da kewaye. Kamar lura, duk da cewa a rayuwar yau da kullum muna nasarar yin amfani da wutar lantarki, kayan, da yawa dokokin da aka samu empirically da kuma kanwar lasa ba. Wannan shi ne daya daga cikin dalilan da ya wuce kima rikitaccen ma'anar. Abin baƙin ciki, har ma da electromotive karfi, da cewa harsashin lantarki injiniya, an hasken a cikin irin wannan hanya da cewa wani mutum wanda ba saba da wutar lantarki, to fahimci wani abu quite wuya.

Directional motsi na cajin barbashi a cikin wani shugaba da aka kira da "lantarki halin yanzu". Kamar yadda ka sani, duk abubuwan da mu kayan duniya hada da kwayoyin halitta. Domin kare kanka da tsabta mu iya ɗauka cewa kowane zarra ne ya wakilci a cikin nau'i na rage da miliyoyin sau da model na hasken rana tsarin: a cikin cibiyar da zuciyar, da kuma a daban-daban nisa daga gare shi a madauwari falakinsu na electrons akwai doguwar.

By wani waje tasiri a wani shugaba kafa wata rufaffiyar kewaye, electromotive karfi ne generated da can ne da lantarki. Impact "darkãke fita" valence electrons daga falakinsu a atoms haka samar free electrons da gaskiya ma cajin ions.

Electromotive karfi wajibi ne don "karfi" cajin zuwa ci gaba da motsi ta hanyar da shugaba da kuma kewaye abubuwa a wani shugabanci. Ba tare da shi, yanzu kusan nan da nan sõmammu. Sort fitar da abin da yake cikin electromotive karfi, zai ba da damar da kwatanta da wutar lantarki da kuma ruwa. Mike bututu sashe - wannan shugaba.

Babu shakka, don samun ta ta motsa a hanyoyi uku: don ƙirƙirar tsawo bambancin (bambanci ko da adadin ruwa a cikin Wuraren) ko karfi famfo. An muhimmin batu: idan muka yi magana game tsaye drop (m bambanci), yake nufi da danniya. Domin EMF wannan motsi "tilasta" saboda waje sojojin shafi, nonpotential.

Wani tushe na lantarki halin yanzu yana da EMF - wannan karfi da cewa tana goyon bayan da motsi na cajin barbashi (a cikin wadannan misalin sojojin matsawa ruwa). Auna a volts.
