Baninzi Izinto zombane banegama lokuchonga okanye iinkqubo zokubachonga. Umzekelo, Iikhowudi zombala wokuxhathisa, eziya kuthi zichonge ukuxhathisa kwii-ohms ezinokuthi zikwazi ukuphuhlisa, kunye nokunyamezelana. Kubalulekile ukuba wazi ezi khowudi malunga nohlobo lokuchasana onalo phambi kwakho xa ungenalo nolunye uncedo ukuze wazi ixabiso lalo, njengemultimeter.
Kwesi sikhokelo sikhawulezayo unako funda ukuqhekeza iikhowudi Abachasi bokufumana ixabiso kwi-ohms kunye nokunyamezelana kwabo, kokubini kukuxhathisa okuqhelekileyo nakwezinye iintlobo zokuchasana ...
Iikhowudi zemibala ezikhuselayo
Kuxhomekeke kuhlobo lokumelana, iikhowudi zemibala zinokwahluka. Ukuze ukwazi ukucacisa amaxabiso kwii-ohms kunye nokunyamezelana kuya kufuneka uyazi ezi tafile zeekhowudi zemibala ye-resistors.
4 kunye neebhendi ezi-5
Ukuxhathisa okuqhelekileyo 4 kunye neebhendi ezi-5, ungasebenzisa le tafile ukuqonda ixabiso layo:
Njengoko ubona, apha ngasentla nangaphantsi unomzekelo wokubala ukuze ubone ukusebenza kolu hlobo lweetafile. Umzekelo, i-5-band resistor enemibala emdaka, emnyama, emnyama, ebomvu, negolide, oko kuya kuthetha ukuba unayo 10 kΩ kunye nokunyamezelana ±5%Oko kukuthi, kunokwahluka kwixabiso elingaphezulu okanye ngaphantsi kwe-5%, kuba azichanekanga.
Ke ngoko, inkqubo ilula, Chonga ukuba yimibala emi-4 okanye emi-5, emva koko uye ujonge umbala ngamnye ngokokulandelelana kwetafile. Kulo mzekelo kuya kuba:
- UMarlon: umbala omdaka kumtya wokuqala uthetha u1. Iyakuba linani lokuqala lamanani aphindaphindwayo ngophindaphinda.
- Negro: omnyama kwisiqwengana sesibini ngu 0. Yinombolo yesibini.
- Negro: umnyama kumtya wesithathu ngu-0.Idijithi yesithathu.
- Rojoumbala obomvu kumtya wesine uphinda-phindo, oya kuthi uphakanyiswe u-10 ukuya kwidijithi ehambelana nalo mbala. Kule meko x 102.
- Dorado: kukunyamezelana ±5%.
Ke ngoko, 100 x 102 = 10.000, Oko kukuthi, 10k.
Ezinye izixhathisi
Njengoko ubona, iikhowudi zombala ze-resistors ze-4 kunye ne-5 stripes aziyi kusebenza ezinye izinto ezichasayo. Umzekelo, ukunyuka komphezulu, potentiometers (eziguquguqukayo), njl.
Izibonelelo
Ukongeza ekubeni nokubanakho ukuba neetafile zangaphambili zeekhowudi zemibala yee-resistors, kuya kufuneka wazi ukuba zikhona Ezinye izixhobo onakho ukuze ukwazi ukubonisana nabo kamnandi naphi na apho ukhoyo. Umzekelo, unamaphepha athile ewebhu okubala okanye ezinye iiapps zezixhobo zefowuni kwizandla zakho:
- Digikey: I-web ine-calculator yamaxabiso ngokwekhowudi yokumelana. Ngendlela, ukuba ujonga eli gama kuGoogle Play okanye kwiVenkile yeApple, uya kubona ukuba nayo ineapp elisebenzisa kakuhle.
- ElectroDocInkqubo ye-Android eneekhowudi zombala ze-resistors kunye nolunye ulwazi malunga neefomula, ukubala, iisekethe, izinto, njl.
- Ikhowudi yeKhowudi yoMbala yoMbalaI-app ekulula ukuyisebenzisa yokubala amaxabiso oxhathiso ngemibala yawo.
