Ixabiso resistor - iindlela zokurekhodisha

Resistors - izinto eesekethe zombane yokuba uxhathiso wawo ukuya kuvala ingxingwa yangoku yombane. Zisetyenziswa kuzo zonke iisekethe zombane, nkqu kakhulu aphantsi. Ukwahlula resistors yi ezi mpawu zilandelayo: amandla uxhathiso ngegama ka iklasi okuchaneka Of engqondweni, njl Kweli nqaku, siza kuqwalasela into efana ixabiso uxhathiso.. Yintoni na? Phantsi ihlelo i element ukumelana kuthetha ixabiso level of ukumelana lwangaphakathi indlela therethrough zombane yangoku. Ixabiso resistor zombane luchazwa ngu Latin R. Eli xabiso idla ubhalwe leeyunithi ezilolo hlobo, njengoko Om. Le yunithi yathiywa emva edumileyo yamachiza waseJamani Georg Simon Ohm, eyaziwa ngokuba umsebenzi wakhe kwinkalo yangoku yombane. Into ekufuneka uyazi ixabiso resistors? Yintoni ukhetha izinto ekunene yeskim eyenzelwe ukuba pick up analog kwefowuni ukulungiswa.

Cinga ukurekhoda iindlela amaxabiso ukumelana nominal kwi izinto yezindlu. Kukho iindlela ezintathu resistors lokumakishela: Digital - kuquka amanani kuphela; ubhalo - na edibene, kunye nombolo ezininzi kunye nonobumba abakhoyo; yaye ekugqibeleni nemibala - kukho uthotho bands ezinqamlezayo ngemibala eyahlukileyo, inani iindledlana yahlukile, ukususela-3 ukuya ku-5.

Further uhlaziye njengoko ixabiso resistor abhalwe kuxhomekeke kudidi element. ukumelana njalo wire-uhlobo Izakhi zezindlu umphanda. Ziphawuleka izinto ezifana ngazo zonke iindlela ezintathu. ukurekhodwa yedijithali lisetyenziswa kuphela resistors, ixabiso kwexabiso elibekiweyo apho ayidluli 999 ohms. Kubonakala ngolu hlobo lulandelayo: 2.0; 220; 750. Iindlela ngokulandelelana 2 ohms, 220 ohms kunye 750 ohms. Okulandelayo uhlobo ukurekhodwa kusebenzisa oonobumba isiphumlisi be-alfabhethi Latin: R - libe linye; K - a Kilo, ie 1000; M - mega, okt 1000000. Kubonakala ukuba le ndlela ushicilelo, ukuze ukufumana ixabiso resistor kufuneka ibe lixabiso lenani liphindaphindwe ixabiso yokoqobo. Umzekelo irekhodi enjalo 220 R - 220 ohms kuthetha; 3K2 - ithetha 3200 ohms; 1M1 - uthetha 1100 ohms.

Lwemibala yexabiso rated lisetyenziswa ngaphesheya ukurekhodwa ilungu lomzimba zezindlu. Le resistors Soviet-ezenziwe yokumakisha ayisetyenziswa i lisisiqalo kwi icala elinye, libonisa imvelaphi ekufundeni. Xa izinto mihla band lokugqibela kusoloko ngegolide okanye isiliva ikhowudi ye-bha, yaye oko kuthetha iklasi ukumelana accuracy (5 okanye-10 ekhulwini ngalinye). Kwimeko ukuba ukumakishwa iqulathe amaqela amathathu kuphela, udidi ukunyamezela elingagqibekanga kwakuthetha-20 ekhulwini. Usebenziso ngekhowudi iqulathe 3-4 bands kwixabiso ezimbini zokuqala iqulathe ixabiso ngegama, kwaye eyesithathu - ixabiso lingabali ezinye. Usebenziso ngekhowudi of emivuzo 5-6 kwixabiso ezintathu zokuqala iquka wesiqhelo, kwaye ngenyanga yesine - ixabiso lingabali ezinye.

Okulandelayo umbono ukumelana - a resistor chip okanye SMD-resistor. Xa ezinjalo resistors ukumakisha na yamanani elingumqondiso. Uthi nje umi: kwi-digital yokumakisha imivo ebonisa ixabiso ngegama, kwaye yokugqibela yi inani amaqanda; sobuntu - amanani amabini ebonisa ihlelo, kwaye ubhalo lokugqibela - ixabiso lingabali ezinye.

In the resistor bume , ukurekhodwa umgangatho kwexabiso elibekiweyo usebenzisa amanani kunye oonobumba be-alfabhethi Latin.
