Resistors kanjani umi wokugubha ezinemibala imivimbo?

Resistor - omunye izakhi eziyisisekelo i wesifunda kagesi elinendawo Resistor njalo noma variable futhi ukhonza ukuguqula kagesi ibe voltage (noma intombi kowesilisa), ukumuncwa ugesi futhi ukwenza eminye imisebenzi eminingi. Lo msuka yokwenziwa kuyingxenye ebalulekile kunoma iyiphi idivayisi. Ngakho cabanga uku ngogesi abanolwazi noma nje ayethanda electronics, kuwusizo kuwe futhi wokugubha resistors imivimbo umbala ukuqokwa nezinombolo ukuze Ukuqhathanisa izici yezingxenye ezahlukene.

Ukukhonjwa resistors kule imidwebo

On the umqondo amadivayisi kagesi Resistor luchazwa ngokuthi isikwele, okuyinto ibekwe phezu incwadi izinhlamvu zesiLatini R. Ngemva uphawu kuyinto nenombolo ye-serial, lapho isici ingatholakala the sebhithi. Ucedzela wesifunda ukuqokwa iqoqo izinombolo ezibonisa ukumelana bokuzisholo. Ngakho, umbhalo oqoshwe R12 100 kungasho ukuthi Resistor 12 isethelwe ohms 100.

Kuvele isici esibalulekile izakhi umthamo wabo. Ukuziba le ndlela, nawe ugijima ingozi lonke uhlelo, ngisho noma incazelo resistors kophawu wawenziwa ngendlela efanele. Umdwebo uzohlonzwa:

• zesi-Roman ezisukela 1 kuya ku 5 Watts;
• strip ovundlile kunani 0.5 watts;
• elilodwa noma amabili imigqa etshekile ngesikhathi amandla 0.25 Watts futhi 0,125 ngokulandelana.

"*" Ngena ibekwa ngemva inombolo ye-serial ezinye resistors. Kusho ukuthi Ukucaciswa ngenhla ayalinganiselwa kuphela. Amanani ngqo uzodinga sithathe bebodwa.

ukuqokwa alphanumeric

Alphanumeric wokugubha isici zobungane ukukhiqizwa Soviet, kanye eminye imikhiqizo esezingeni lomhlaba. resistors Ukumaka amazwe kanye nemikhiqizo yasekhaya ungase uqale njengoba isibalo futhi uphawu. Kulokhu amayunithi esiqokiwe kanje:

• uphawu "E" noma «R» uthi kwenani eliyimali obonakaliswe ohms;
• incwadi "M" lisitshela ukuthi ukumelana lubonakaliswa megohms;
• ngemvume "K" kuthiwa kwahambisana by wonke amanani ezinombolo obonakaliswe kiloomah.

Uma uphawu ibonakala ngemuva izinombolo, wonke amanani obonakaliswe wonke amayunithi (33E = 33 ohms). Ukuhlonza incwadi ingxenyenamba pose amadijithi (K55 = 0.55 kilohms = 550 ohms). Uma uphawu ukwabelana, lo resistivity wezwakalisa njengoba inamba amagugu nge wamaqhuzu ingxenye (1M3 = 1.3 megohms).

umbala ihlelo

Ubude ezinye "ukuzabalaza" kuyinto amamilimitha angu ezimbalwa kuphela. Sebenzisa uphinde ubone izinhlamvu nezinombolo kule ngxenyekazi akunakwenzeka. Ukuze uqhathanise ncenye is esetshenzisiwe wokugubha resistors imivimbo ezinemibala. Eyokuqala amaviyo amabili zihlale obhekene ihlelo. Abanye ku emapheshana yasebhange anencazelo:

• e mshini 3- noma 4 kwindlela-dash yesithathu ichaza Okuphindaphinda, kanti owesine - ukunemba;
• 5-indlela abizwa umbala lesithathu kubonisa ihlelo, sesine - multiplier, eyesihlanu - ukunemba;
• kwindlela lesithupha likhombisa Coefficient lokushisa ukumelana noma ukuthembeka cell, uma mkhulu kunabanye.

Umbala ibha likhombisa amanani ezinombolo eliyifa lawo. Ukubhekana naleli thebula kuzosiza resistors wokugubha lapho umthunzi ngamunye oluhambisana isici esithile, noma sibalo. Ngokwesibonelo, siba Resistor nge imivimbo obomvu, oluhlaza, ensundu okwesibhakabhaka. Wokufunda inshokutsi yemagama, siyazi ukuthi sibhekene Resistor 25 ohms * 10 = 250 ohms ukunemba 25%.

ukulandelana emapheshana

Kanjani ukuze kunqunywe ukuthi yiziphi ohlangothini ukuqala emagama? Ngemva kophawu resistors imivimbo ezinemibala kungenziwa ukukhishwa zombili izinkomba. Ukuze ugweme ukudideka kulesi, kubalulekile ukukhumbula ezinye imithetho elula:

1. Uma kukhona amaviyo amathathu kuphela, owokuqala iyohlale elise eduze onqenqemeni kuka zokugcina.
2. Izakhi 4-indlela isiqondiso Ukufundwa kufanele kunqunywa isiliva noma umbala yegolide - bayohlala njalo akhiwe closer phetho.
3. Kwezinye izimo, kumele ufunde ukuze bathole ukubaluleka uchungechunge bokuzisholo. Uma kungenjalo, kubalulekile wokufunda olunye uhlangothi.

Ikesi ahlukene iyona indawo jumper black emzimbeni. Kusho ukuthi-elementi ayinayo ukumelana futhi lisetshenziswa njengendlela jumper. Manje ngoba sewuyazi ukuthi indlela ukufunda resistors wokugubha ezinemibala imivimbo, nezinkinga nge kwencazelo element okuzisholo ungeke ube.
