zhinji Zvemagetsi zvigadzirwa vane mazita ekuremekedza kana masisitimu ekuvaziva. Semuyenzaniso, resistor mavara macode, iyo inozoona kuramba mukati ma ohms iyo ivo vanokwanisa kusimudzira, pamwe nekushivirira. Izvo zvakakosha kuti uzive aya macode kuti uzive nezverudzi rwekupokana iwe unayo pamberi pako kana iwe usina rumwe rubatsiro kuti uzive kukosha kwayo, senge multimeter.
Muchirongwa ichi chinokurumidza iwe unogona dzidza kutyora makodhi yeavo vanopikisa kuti vawane kukosha mu ohms uye kushivirira kwavo, zvese mune zvakajairika resistors uye mune mamwe marudzi eanopokana ...
Resistor kodhi dzemakodhi
Zvichienderana nerudzi rwekupokana, makodhi emavara zvingasiyana. Kuti ukwanise kutsanangura hunhu mu ohms uye kushivirira iwe unofanirwa kuziva aya matafura emakara kara eanopikisa.
4 uye 5 mabhendi
Kune zvakajairika zvinodzivisa zve 4 uye 5 mabhendi, unogona kushandisa tafura iyi kuona kukosha kwayo:
Sezvauri kuona, zvese kumusoro uye pazasi iwe une muenzaniso wekuverenga kuti iwe ugone kuona mashandiro erudzi urwu rwematafura. Semuenzaniso, iyo 5-bhendi inopikisa ine mavara brown, nhema, nhema, tsvuku, uye goridhe, zvinogona kureva kuti une 10 kΩ uye kushivirira kwe ±5%, ndiko kuti, zvinogona kusiyanisa iwo kukosha pamusoro kana pazasi pe5%, sezvo iwo asiri iwo chaiwo.
Naizvozvo, maitiro zviri nyore, ingoona kuti iina kana mashanu mavara, wobva waenda unotarisa rumwe ruvara muhurongwa hwetafura. Mumuenzaniso uyu zvingave:
- bhurawuni: shava mumutsara wekutanga zvinoreva 1. Ichave iri nhamba yekutanga yenhamba inofanira kuwedzerwa nemuwanda.
- Nhema: dema mumutsara wechipiri ndi 0. Ndiyo digit yechipiri.
- Nhema: dema mumutsara wechitatu iri 0. Tatu digit.
- Red: iyo tsvuku mumutsara wechina ndeyekuwedzera, inozove gumi yakasimudzwa kune iyo digit inoenderana neiyo vara. Mune ino kesi x 102.
- Dorado: kushivirira kwe ±5%.
Naizvozvo, 100 x 102 = Zviuru gumi, ndiko kuti, 10.000k.
Zvimwe zvinopesana
Sezvauri kuona, iwo mavara emakodhi eanopikisa e4 uye mashanu maronda haazove anoshanda mamwe ma resistor. Semuenzaniso, kune pamusoro pegomo, potentiometers (akasiyana), nezvimwe.

Pamusoro pekukwanisa kuve nematafura epamberi emakara kodhi eanopikisa, iwe unofanirwa kuziva kuti iwo aripo Imwe zviwanikwa chauinacho kuti ugone kuvabvunza zvakanaka kubva chero kwauri. Semuenzaniso, une mamwe mapeji ewebhu ekuverenga kana mamwe maapplication emafoni nhare paruoko rwako.
- Digikey: webhu ine Calculator yemitengo zvinoenderana nekodhi yekudzivirira. Nenzira, kana iwe ukatsvaga zita iri paGoogle Play kana paApp Store, uchaona kuti iine zvakare app yekuishandisa zvakanyanya.
