Kana isu tine maresitorendi akati wandei munharaunda yemagetsi, iyo zvakafanana nemishonga, inova inodzivirira imwe chete inogona kutsiva mamwe ese mudunhu rakareruka. Kana iwe uchida kuziva zvakawanda nezve izvi, ramba uchiverenga kuti uzive zvese nezve Kupikisa kwakaenzana uye maverengerwo ayo.
Maverengero ekuenzana kuramba munhevedzano.
Chii chinonzi kuramba kwakafanana?
Tinofanira kuyeuka kuti kukosha kwekupikisa kwemagetsi, maererano nezvakataurwa pamusoro apa, kuti zvive zvakanyatsogadzikana, zvinofanirwa kunge zvakadaro zvokuti magetsi, magetsi uye kupikisa kwese kweimwe dunhu kwakafanana neiyo yedunhu rekutanga. nezvose zvinopikisa zvepakutanga, saka ndiwo mamiriro ekuti ive yakaenzana.
Saizvozvo, iwe unofanirwa kuyeuka kuti yakaenzana yemagetsi kuramba ndeye kuramba kumwe chete kunotsiva vamwe kurerutsa maverengero mukati memaseketi. Naizvozvo, ihwo hunyanzvi hwemasvomhu hunoita kuti udzidze maitiro edunhu kuburikidza neimwe iri nyore ine resistor imwechete.
Yakaenzana resistors munhevedzano
Kana tiine dunhu rine maviri kana anopfuura resistors munhevedzano yakaenzana kune imwe chete resistor ayo ukoshi ndiko uwandu zvose resistors munhevedzano uye achanzi Total Equivalent Resistance. Kana, semuenzaniso, isu takaunzwa nevatatu vanopikisa munhevedzano sepamufananidzo wapfuura, kuti tiverenge kuenzana kwavo kana kuwanda, isu tinongofanira kuwedzera ivo:
- Yakaenzana Re = 10 + 5 + 15 = 30Ω
Saka magetsi acharamba ari 6V. Iyo yakaenzana Re yaizova kupikisa kwese kwedunhu, uye kana tikaverenga kuwanda kwese kwedunhu kunenge kwakafanana nerekutanga redunhu rinonzi rakaenzana redunhu. Izvo zvinodikanwa kuyeuka kuti kana uchitaura zvakaenzana hazvireve kuti zvakafanana, iwo akasiyana asi akaenzana maseketi, sezvo iwo ese voltage, kupikisa kwese uye kusimba kwese kwakafanana.
Mukati medunhu rakaenzana, kushandisa Mutemo weOhm, huwandu hwese hwedunhu hunowanikwa semhedzisiro, kuverenga: Ini yakazara = VT / Rt = 6/30 = 0,2A. Izvi zvichave zvakafanana mumaseketi ese ari maviri. Saka ikozvino, kukwanisa kugadzirisa dunhu rekutanga zviri nyore, sezvo tichiziva kuti kusimba kweseti kwakakosha sei, nekuda kwe zvakafanana nemishonga zvatakaverenga kuburikidza nedunhu rechipiri.
Kupikisa kwakaenzana mukuenderana
Mukati memaseketi akafanana, kuverenga kuramba kungave kwakaoma, asi kwete kufira. Kana isu tiine kupikisa kwakaenzana kweanopikisa akati wandei akafanana, isu tinofanirwa kuiverenga neformula ye:
- Rt = 1/1-R1 + 1-R2 + 1-R3 +…
Kunyangwe ichitaridzika zvakanyanya kuomarara pane kuve munhevedzano, inofanirwa kusangana nemamiriro ekuenzana kuburikidza neforoma yakataurwa. Nekutsiva kukosha kweR1, R2 uye R3, kupikisa kwakaenzana kunoverengerwa; Equivalent Re = 2,73, tichifunga kuti kupikisa kwese muparallel current kuchave kushoma pane zvakatevedzana.
Resistance in parallel.
Kune rumwe rutivi, kana huwandu hwehuwandu hwedunhu huchiverengwa, kuverenga kwaunotipa kuchava kwakafanana neyekare chekare ne3 zvinopikisa: Itotal = Vt / Rt = 5 / 2,73 = 1,83A.
Iye zvino tinogona kuverenga mafungu pane imwe neimwe yedunhu rekutanga sezvo isu tichiziva voltage mubazi rega rega (5V mairi nekuti iri kuenderana) uye tinoziva kuramba mubazi rega rega (R1, R2 kana R3).
- I1 = V/R1; I2 = V / R2; I3 = V / R3; Huwandu hweiyo 3 intensities ichafanirwa kufanana neItotal yakaverengerwa kare.
Kana chinyorwa ichi chave chichibatsira kwauri, tinokukoka iwe kuti uone rumwe ruzivo nezvemagetsi kubva pawebhusaiti yedu, senge Normalized masimba Ndezvipi uye ndeapi marudzi aripo? Tichakusiirawo vhidhiyo inotevera kuti udzidze zvakawanda nezvenyaya iyi.
