Internal nemishonga uye ayo chaiko zvinoreva

Mumwe ano bhuku iine womukati nemishonga pachavo. The yemagetsi redunhu - a namahwindo redunhu pamwe vatengi dzakasvikwa voltage rikashandiswa. Mumwe gandiwa ane kwokunze uye zvemukati nemishonga.

Kwokunze nemishonga kwemutariri yose inonzi mutengi uye conductors, uye dzomunyika kurwisa inobva kupi.

Kana pari bhuku iri wemagetsi muchina, ipapo ayo womukati impedance rakakamurwa chinoshingaira, inductive uye capacitive. The vanoshingaira kondakita zvinoenderana kureba kwayo uye ukobvu, uye mashoko iyo muitisi, uye ayo ezvinhu. Inductive kunobva coils inductance (ayo nokukura emf) uye capacitance kwakaita pakati majana ose windings. Hazvina zvikuru diki. Kana bhuku iri kwakajairika bhatiri, kuti kurwisa nokuda kwayo electrolyte zvakare akasika.

Current - iri rinotungamirirwa kufamba nezvimedu uye nemishonga - ndiko kuti kusika chipingamupinyi chacho kufamba. zvipingamupinyi vakadaro nawo electrolyte uye vatungamirire mahwendefa ane mabhatiri, mune pfupi, pose pane kuitika.

Nokuti pane womukati nemishonga iri bhuku, hazvibviri kudavira kuti makakatanwa ari cheni - ichi ndiko rakazara electromotive simba. Chokwadi, kuti voltage donhwe panguva panobva inogona kungosiyiwa, asi kana bedzi zviri kunyora nezvavo.

Kana romugove cheni marefu dzenzvimbo, kuti chinouraya voltage haagoni kunzi kwechokwadi electromotive simba. The kuitika mu kunobva - ndicho chiratidzo voltage ichidonhedzera imomo. Panyaya iyi, mutemo Kirchhoff, iyo inoti kuti wechokwadi EMF cheni - ndiko kuwanda voltage anodonhedza muzvinhu zvose, kusanganisira vaya vari kupi. A yemaitiro zvakanyorwa se:

E = ΣU + Ir R

apo:

E - zvachose electromotive simba redunhu;
U - voltage donhwe pamusoro redunhu zvikamu;
VaIri - womukati iyezvino zvinoberekwa kunobva;
R - womukati mabviro impedance.

Kuti tinzwisise zvinorehwa womukati kurwisa ari kupi chaiko, panofanira kuva chiitiko. Pakutanga akayera simba electromotive kunobva. Izvi zvinoitwa unobatanidza munhu voltmeter kuti bhatiri, izvo zvisiri pasi mutoro. Shure kwaizvozvo, duku nemishonga kwakabatana munguva dzino uye ammeter yakatarwa. Saka, kuitika achazivikanwa, apo zvakakosha zvakare kuyera voltage pasi mutoro.

Kunyatsovatsanangurira tsika zvose nyore kuona zvemukati nemishonga. Kuti aite izvi, kutanga pakutsvaga voltage donhwe bhatiri. Kushandisa fomura

Ur = EU

Tichiitira Masvomhu.

In fomura ichi:

Ur - inodonha dzomunyika tsime voltage kuramba;
E - voltage (electromotive simba) akayera panguva kunobva pasina mutengi;
U - voltage, akayera zvakananga pamusoro kurwisa.

Saka, dzomunyika kurwisa rinowanikwa kubudikidza mutoo:

R = Ur / I

Dzimwe nyanzvi hanya kukosha ichi, tichifunga kuti hazvigoni kungotariswa nokuda diki ukoshi. Zvisinei, tsika chinoratidza kuti nekuda Masvomhu yakaoma womukati kurwisa kukanganisa zvikuru kwokupedzisira mugumisiro.
