Yiziphi izinhlobo ezahlukene resistors

Lapho edala imidvwebo lobuchwepheshe imininingwane edingekayo. Resistors kukhona phakathi ebaluleke kakhulu. Kunzima ukucabanga isikimu ngisho izingxenye ezinhlanu, noma ngabe bathola isicelo sabo.

Uyini Resistor

Igama elithi sidalwe sibonga Latin "Resisto", okungase elihunyushwe ngokuthi "ukumelana nayo." The main izakhi Umngcele we-data, esinikela Okuthakazelisayo ukumelana bokuzisholo. It is kulinganiswa ngo ohms (inombolo ohms). Amanani Okuzisholo ekhombisa kudivayisi izindlu. Kodwa isibalo sangempela kungaba ukuhluka. Ngokuvamile, lokhu ehilelekile ezihilela ukusetshenziswa amakilasi nokunemba tolerances. Lezi esizoyicabangela manje. Uma ungeke uluqonde okuthile mayelana nezinhlobo resistors, isithombe ukusiza ukukulungisa.

Kuqala amakilasi ukunemba kanye tolerances

Ngokuvamile, uJesu oyisibonelo esikhulu kunazo isithakazelo amakilasi. Ziyakwazi ezintathu:

1. Okokuqala. Uhlinzeka ngeziphambeko ezingaba amaphesenti angu-ezinhlanu kusukela wathi value bokuzisholo.
2. Okwesibili. Uhlinzeka ngeziphambeko ongafinyelela amaphesenti ayishumi yenani bokuzisholo.
3. Okwesithathu. Lezi zihlanganisa amadivayisi usayizi ngeziphambeko ongafinyelela amaphesenti amabili yenani bokuzisholo.

Godu kuthiwani nengabe ngeziphambeko kangaka azamukeleki? Kukhona resistors ngokunemba, okunikeza ukubukwa kwisilinganiso esibekiwe sika-umehluko:

1. 0.01%.
2. 0.02%.
3. 0.05%.
4. 0.1%.
5. 0.2%.
6. 1%.
7. 2%.

ezinye izinketho

Okubaluleke okuphawulekayo isici Ukukhetha for kwemigomo wesifunda anciphisa inani lezimoto voltage ukusebenza, ngokulinganisa amandla ukushabalalisa kanye lokushisa Coefficient ukumelana. Isibalo yokugcina ibonisa ukuthi izinguquko esikalini degree sizothinta ukusebenza idivayisi. Kulesi sibalo kungase kukhule noma kwehle kuye impahla asetshenziswe ekukhiqizeni. Kulinganiswe ngo amandla ukushabalalisa sikhombisa isici ukusetshenziswa umngcele. Uma isici supply mkhulu kunezinhliziyo zingahlungwa, le Resistor umane zishe. Ngokunciphisa voltage zokusebenza bona kube inkomba ezinjalo, lapho ukusebenza onokwethenjelwa apharathasi zizonikezwa.

Izinhlobo ezinkulu resistors

Ziyakwazi ezine:

1. Non-ezilungisiwe:

a) njalo.

2. Okungalawulwa:

a) Ukunquma;

b) eziguquguqukayo.

3. Thermistors.

4. Photoresistors.

resistors Okungalawulwa okuhleliwe okwengeziwe ihlukaniswe kungekho / wire. Ngo uhlobo wesibili okwengeziwe isilonda wire abe esikhulu resistivity. Ukubonisa resistors ilungiswe ngendlela iinkwere, okuyizinto ezibalulekile iziphetho ethize. Inani ovumelekile amandla ukushabalalisa icaciswe ngaphakathi sibalo Jomethri. Uma ukubaluleka ukumelana ku ezahlukene ohms 0 kuya 999, amayunithi wokulinganisa kungukuthi ngokuvamile ecacisiwe. Kodwa uma lesi sibalo ezingaphezu kwenkulungwane, noma million, namagama asetshenziswa ohms futhi megohms, ngokulandelana. Uma lesi sibalo wabonisa kuphela mayelana noma kungase ukushintsha phakathi izilungiselelo, engeza *. Ngenxa yalokhu izinhlobo ezahlukene resistors Amapharamitha ayehluka kalula.

izakhi variable

Siyaqhubeka cabangela izinhlobo resistors. Lolu hlobo idivayisi angasahlelwa ngokuthi kwenombolo. Bona ukumelana kungaba isukela zero nenani bokuzisholo. Zingabonisa / wire. Uhlobo lokuqala kuyinto enamathela conductive ukuthi lisetshenziswa ipuleti Kwe-dielectric Heating njengoba arc, lapho contact 'azithathe idluliswa ukuthi ogibele oluvala amasondo. ukuhamba kwayo Kwenziwa uma uthanda ukushintsha ukubaluleka ukumelana. Kuye eziningi izici lokhu kulungiselelwa kungashintshwa e ubuhlobo obunjalo:

1. Ukuthuthukiswa.
2. Logarithmic.
3. Exponential.

kusilungisi resistors

Abanaso eksisi projecting. Ukushintsha kwemigomo lolu hlobo resistors kungenzeka kuphela ukufakwa kokumqoka kuphela noma othomathikhi / idivayisi mechanical ukuthi ungakwazi ukwenza umsebenzi walo. Lokhu nezinhlobo yangaphambilini ye resistors esetshenziswa ezimweni lapho umuntu emandla ekulawula, isibonelo, izipikha.

thermistors

Ngakho ngokuthi izakhi Semiconductor, lapho wesifunda kagesi lapho inkomba ezifana ukumelana siyahlukahluka lokushisa. Lapho ezibeka phansi izithelo zalo. Uma izinga lokushisa lehla, ukumelana kwandisa. Uma inqubo ijika lithuthela uhlangothi (kokukhulisa inyuka), khona-ke lokhu kubizwa ngokuthi PTC isici.

photoresists

Ngakho ngokuthi izakhi, lapho Inkomba ipharamitha kuyahlukahluka bedle ukukhanya (futhi kwezinye izimo, futhi kagesi) evela ngaphandle. Njengomthetho, wasebenzisa photoresists kokuba umphumela Photoelectric omuhle. Ukumelana yabo incipha lapho bavezwa ukukhanya. Photoresists abe design elula, usayizi amancane sensitivity high, okuvumela ukusetshenziswa kwabo Photoelectric, tibali, ukulawula, nemithethonqubo kanye nokuphathwa amadivayisi, izinzwa namanye amadivayisi amaningi.

isiphetho

Lapha kukhona resistors ezinjalo, izinhlobo, injongo, Umgomo we operation yalezi amadivaysi.
