A nyore yemagetsi redunhu

Munhu, kana iye, Chokwadi, haana kukanda mapfumo zvakanakira yebudiriro, yakapoteredzwa zhinji magetsi namano. Enda kure mienzaniso havadi: TV, runhare, vakawanda vanhuwo incandescent rambi , Nezvimwewo Panobva mano izvi zvose ndicho zvemagetsi vematunhu.. zvisinei mabhuku mabhuku akawanda kupa zvakafanana tsanangudzo,, panyaya nyore mhando. Sei zvakadaro, nokuti ano zvemagetsi zvokuti zvakaoma kuti basa ravo riri akavimba nomudzimu makombiyuta hurongwa? Zvechokwadi, chinoshamisa, kunyanya kufunga CPUs pachavo makombiyuta nemamiriyoni avo transistors - riri aripo yemagetsi redunhu DC. Chikonzero pamusoro kutsunga anoitwa ndechokuti chero kunyange yakaoma, kuti hushande anogona kupiwa nenzira muzvizhinji kuti zvokutanga zvinoriumba. Zviya, ichi Ndokusaka zvinobvira kuita zvakafanira Masvomhu uchishandisa anozivikanwa Masvomhu.

Saka, takasarudza nyore uye zvakaoma kunzwisisa. Zvino ngatiite kutsanangura chii redunhu yemagetsi. Kuti kuita zvakawanda pachena, funga muenzaniso nyore - imwe furashiraiti. Uye kwete neumwe anoshandisa kuzvidzora Chip (rudzi nokuchinja, kuvheneka, etc.), uye rakajairika - ane bhatiri, rimwe girobhu racho uye Toggle chinja pamusoro. It rine dzimba ine pacharo itsime danda, mumwe chinja mupanda kuti bhatiri vaviri vokukurukura. Mushure kuisa mashoko bhatiri kupinda redzimba uye nekudzvanya munhu chinja, unogona kuwana rakajeka achitaura zviedza hwihwinyara. Zvaakanga akaita zviito izvi, isu ndakazvitema chete chinonzi wemagetsi vematunhu (ari nyanzvi akariposhera - vakaungana zano). The kuitika tsime kuti Magetsi (bhatiri) vakamhanyira mugwara: kutaura zvakanaka danda - kondakita tumbler - Lamp - kunaka danda. Izvi zvinonzi "nyore zvemagetsi redunhu." In muenzaniso ane furashiraiti zvinhu zvitatu: tsime EMF, chinja uye mwenje. Zvinofanira kucherechedzwa kuti kufamba maerekitironi (kuitika) zvinokwanisika chete mune namahwindo redunhu, saka kana iwe chinja kuti patsanura uye kutyora cheni, ichanyangarika, kunyange kunobva voltage anoramba. Sezvineiwo, pezvakaitwa zvose inogona kurondedzerwa nokuenzanisa kwete chete kuburikidza magetsi asiwo by voltage, simba, EMF.

Universal chishandiso pakuverenga - mutemo Ohm vake. Muchiitiko chino, zvinoita sokunge:

I = E / (R + R),

apo I - ano, Amperes; E - EMF Volta; R - nemishonga girobhu racho ohms; R - EMF bhuku impedance, ohms. Sokushandiswa muenzaniso matambudziko kuramba ari kondakita uye Toggle chinja hauna zvaisanganisira, sezvo kunyora nezvavo.

Saka, magetsi wedunhu uye yenhengo dzayo zvingasanganisira munhu simba tsime, resistors, capacitors, inductors, semiconductors, uye nezvimwewo. Uyezve, ichi zvose zvinofanira kwakabatana pamwechete conductors kuti vanoumba chinoramba nzira uno chokubuda.

Dunhu Simple vari rakakamurwa yakananga uye mapazi. Muchiitiko chokutanga, vose constituent okunze inopfuura chete pari (yemanyorero nokuti Serial kubatana vatengi). Kana yechipiri riri mberi akawedzera imwe kana mapazi akawanda chokuita funga nyore redunhu kuburikidza nodes. In ichi yakavhenganiswa remubatanidzwa kuumbwa redunhu okunze, uye saka kukosha kuitika kuyerera davi rimwe nerimwe riri akasiyana. Pano, bazi - chikamu chino redunhu, zvose zvinhu izvo runoyerera chete uno, uye pakatarisana kumigumo izvo zvakabatanidzwa kune nodes maviri. Nokudaro, raiva pedyo nebundu - ndiwo pfungwa redunhu umo wekuita matavi matatu kana kupfuura. In redunhu chati nodes kazhinji chete kureva pfungwa kuti hwezvekukurukurirana kugamuchira (kuverenga).
