Ndi mphamvu electromotive Kodi

M'nkhani ino tikambirana kodi electromotive mphamvu mphamvu zoyendetsera nanga ubale wake ndi magawo ena a dera la. Monga onani, ngakhale kuti tsiku ndi tsiku tiyenera bwinobwino pogwiritsa ntchito zipangizo zamagetsi, malamulo ambiri akhala anachokera empirically ndi kuitenga mopepuka. Ichi ndi chimodzi mwa zifukwa matanthauzo kwambiri kwambiri. Mwatsoka, ngakhale mphamvu electromotive, kuti maziko a ukachenjede magetsi, ndi kuunikiridwa mwa njira yakuti munthu amene si bwino magetsi, kumvetsa chinachake kovuta. Tikufotokozera nkhani mothandizidwa ndi mawu omveka lililonse, ndi zitsanzo.

Polozera kayendedwe ka particles mlandu wochititsa ndi akutchedwa "magetsi inawadutsa". Monga inu mukudziwa, zinthu zonse za mdziko zathu zakuthupi wapangidwa maatomu. Chifukwa cha momveka tikhoza kuganiza kuti aliyense atomu ukufanizidwa mu mawonekedwe a yafupika mamiliyoni ambiri chitsanzo cha dongosolo la zowalitsa: pakati pachimake, ndi pa mtunda osiyana kwa izo m'njira zozungulira za ma elekitironi umakhudza.

Ndi amadza kwina mu wochititsa ndi kupanga dera chatsekedwa, electromotive mphamvu kwaiye ndipo pali zamagetsi. Impact "agogoda kunja" valence ma elekitironi ku zawozo mu ma atomu kotero opangidwa ufulu ma elekitironi ndi ayoni ndithu mlandu.

Electromotive mphamvu n'kofunika kuti "mphamvu" milandu kupitabe kudzera kondakitala ndi nyengo dera m'njira zina. Popanda panopa pasanapite nthawi kuuzimitsa. Longosola kodi mphamvu electromotive, adzalola kufanana kwa magetsi ndi madzi. Molunjika chitoliro gawo - wochititsa izi. maphwando ake awiri zimakhalira mu matupi madzi. Bola ngati amaudindo madzi Madamu ndi ofanana ndipo palibe kupatuka, madzi mu chitoliro ndi n'kupuma.

Mwachionekere, kuti iye kusamukira ku njira zitatu: kulenga msinkhu kusiyana (kukondera kapena kuchuluka kwa madzimadzi mu malo a) kapena mphamvu mpope. Zikusonyezanso kuti ngati tikukamba za dontho ofukula (kusiyana kuthekera), izo zikutanthauza nkhawa. Pakuti EMF gulu lomwelo "amakakamizidwa" chifukwa mphamvu kunja zokhudza, nonpotential.

njira iliyonse ya magetsi ali EMF - mphamvu zothandiza kayendedwe ka particles mlandu (otsatirawa mphamvu kufanizira kusuntha madzi). Amayezedwa volts. Dzinali odziwikiratu: EMF amadziwika ntchito Ufumuyo kwa chigawo cha unyolo wa asilikali kunja kuti kuchita kusamutsidwa lililonse mlandu wagawo ku mtengo wina ndi mzake (pakati pa malo). Ndi numerically wofanana ndi chiŵerengero cha ntchito ya magulu kunja Ufumuyo mtengo wa mtengo makina.

Mwanjira muyenera emf gwero akhoza linachokera ku lamulo la kusamala mphamvu ndi katundu wa kondakitala. Mu chatsekedwa dera ntchito wakumunda kayendedwe ka milandu ndi ziro. Komabe, wochititsa ndi usavutike (ndi mphamvu yaikulu panopa umadutsa izo pa nthawi wagawo). Kutsiliza: dera ayenera kupezeka chiwerengero cha mphamvu kunja. Anati kunja asilikali - ichi maginito magudumu, ndi ma elekitironi zosangalatsa mosalekeza; mphamvu zochita mankhwala mabatire.

Mphamvu electromotive wa kupatsidwa ulemu anali woyamba anati experimentally mu 1831 ndi wasayansi Faraday. Iye anapeza kuti kondakitala-kusinthitsa mizere mwamphamvu alternating maginito, ndi magetsi. Ndinakumana ndi munda malipoti a ma elekitironi lakunja mu maatomu wa mphamvu kusowa kwa iwo, kuwalamulira kusiya ndi kuyamba kusuntha (panopa utuluke). Kumene, kayendedwe mwachindunji particles kulibe (sangathe kukumbukira relativity wa axioms magetsi). M'malomwake, pali kuuzana particles pakati pa maatomu yapafupi.

Yopangidwa ndi mphamvu electromotive - izo ndi khalidwe mkati mwa gwero mphamvu.
