Resistor tsika dzavo izita

Resistor - chinhu redunhu, iyo inoshanda kuderedza kuitika mairi. Uyewo, resistors inoshandiswa kuderedza kunetseka mune dzimwe nzvimbo uye nekupatsanurwa kupinda kwayo zvinoriumba iyezvino. In nemagetsi matunhu resistors vari runotaurwa rectangles duku ine peya nembambo (rimwe kumativi akasiyana maviri). Kunze resistors vanomirirwa wakaputsika mutsetse.

Resistors huru parameters matatu:

1. Standard nemishonga (resistor tsika).
2. Kubvumidza.
3. Power nounzenza.

Resistor tsika - kukosha kwavo chezita nemishonga, kureva mutengo hwacho nokuda mugadziri. Chezita nemishonga kunoonekwa mune ohms. Resistors zvinoshandiswa anenge maindasitiri ose, ane zvishoma magetsi namano. Izvi zvinotisvitsa hombe zvakawanda nemishonga tsika. Zvisinei, pane resistor tsika, zviri kudenga nepanyika.

Zvokuzvigadzirira simbi dzomuchina resistor neumwe chaiwo chezita ukoshi zvakaoma chaizvo, saka shandisa kukosha ichi somunhu shiviriro. Somuenzaniso, kana munhu akanyatsojekesa chezita nemishonga akaenzana 10 ohms, mune chokwadi zvaizova anenge 10,1 9,98- ohms. Uku kunonzi zvichibvira kukanganisa tolerances uye akayera somunhu chikamu.

Power nounzenza - chimwe chezvinhu zvinokosha kusarudza resistor. Tsanangura zvinoreva kupiwa ukoshi. A resistor kuburikidza nenhengo zvemagetsi iyezvino ari akaramba neshungu. Heating kunobva magetsi chinzvimbo. Mumwe resistor ane mumwe tembiricha muganhu kupfuura iyo overheats uye anopisa akabuda. Nounzenza - ndiko kunokosha simba electric ano, apo resistor kuchapisa. Kufanana zvinokosheswa resistors, simba nounzenza - riri kuramba kuti mumwe nomumwe wavo. It zvinoratidzwa mugadziri. On nemagetsi matunhu akaparadza simba resistor zvinofanira kutaurwa. Nokuti kwayo rokuti akashandisa vachida, chinjikira uye tote nemitsetse. Kubva mufananidzo pamusoro resistor kuvake mitsetse dzinokosha anofambidzana kureva zvakasiyana simba tsika. Typical tsika mu zvirongwa duku siyana pakati 1/8 watt uye watts or shanu. Power nounzenza chero resistor anogona akaverenga kubva mutemo Ohm nokuda subcircuit. Kuti vanokurondedzera, unofanira kuziva kuitika mudunhu uye aizviti kukosha resistor.

ratings vose kwezvipimo nemishonga. Ndiko, pane zvimwe mureza resistor tsika. tsika Ivavawo, iri dzikarongwa mumitsara pechiso tsika resistors. Nokuti dzino vakadaro DC muenzi 6: E6, E12, E24, E48, E96, E192.

Nokuti ano variables anoshandiswa chete neapo pokutanga E6 uye E3. The zviverengo mazita mitsara vanomiririra uwandu zvichibvira ratings munyaya dzino. Somuenzaniso, vakawanda masangano E6 hakungorevi zvinogoneka kutevera nemishonga: 1.0; 1.5; 2.2; 3.3; 4.7; 6.8.
