Cov neeg tiv thaiv tswj hwm tus nqi tam sim no ntws hauv hluav taws xob. Cov neeg tawm tsam nthuav tawm qhov kev tawm tsam, lossis cuam tshuam, rau cov hluav taws xob hluav taws xob thiab txo tus nqi tam sim no uas tau tso cai ntws. Resistors tau siv rau kev teeb tsa yooj yim thiab txhawm rau tiv thaiv cov khoom siv hluav taws xob uas tuaj yeem puas los ntawm kev tau txais tam sim no. Cov neeg tawm tsam yuav tsum tau ua kom zoo thiab tsis ua haujlwm kom ua tiav cov haujlwm no. Siv cov lus qhia no los kawm paub yuav ntsuas tus tiv thaiv li cas.
Cov kauj ruam
Kauj Ruam 1. Tshem lub hwj chim los ntawm lub Circuit Court uas muaj cov resistor
Qhov no tuaj yeem ua tiav los ntawm kev tshem nws los ntawm lub hauv paus lossis tshem lub roj teeb yog tias nws yog lub cuab yeej nqa tau. Nco ntsoov tias qee lub cuab yeej tseem tuaj yeem raug them nrog qhov muaj peev xwm tsim teeb meem txog rau feeb tom qab tshem nws lub zog!
Kauj Ruam 2. Rho tawm tus resistor los ntawm Circuit Court
Ib qho kev sim ntsuas tus tiv thaiv uas tseem txuas nrog rau hauv Circuit Court tuaj yeem ua qhov ntsuas tsis raug, raws li ib feem ntawm Circuit Court kuj tseem tuaj yeem ntsuas.
Tshem tawm ib qho kawg ntawm tus tiv thaiv los ntawm Circuit Court. Nws tsis muaj teeb meem twg qhov kawg ntawm tus tiv thaiv tau txuas nrog. Disconnect tus resistor los rub lub resistor. Yog tias cov tshuaj tiv thaiv tau muab tso rau hauv qhov chaw, yaj cov kab laug sab nrog cov qib qib hluav taws xob thiab rub cov tshuaj tiv thaiv dawb siv rab koob me me ntawm lub qhov ntswg. Cov xaim tooj liab muaj nyob ntawm cov khoom siv hluav taws xob thiab cov khw muag khoom nyiam
Kauj Ruam 3. Tshuaj xyuas tus tiv thaiv
Yog tias tus tiv thaiv pom cov tsos mob ntawm kev ua kom dub lossis ua rau khaus, nws yuav raug puas tsuaj los ntawm kev ntws ntau dhau. Ib tus tiv thaiv uas qhia pom dub los yog charring yuav tsum tau hloov thiab muab pov tseg.
Kauj Ruam 4. Nyeem tus nqi resistor kom pom kev
Tus nqi tiv thaiv yuav raug luam tawm ntawm tus tiv thaiv. Cov tshuaj tiv thaiv me me tuaj yeem muaj lawv cov txiaj ntsig qhia los ntawm cov xim coded bands.
Nco tseg qhov ua siab ntev tiv taus. Tsis muaj tus tiv thaiv tus kheej yog tus nqi qhia rau nws. Kev ua siab ntev qhia tias ntau npaum li cas cov ntawv luam tawm yuav txawv thiab tseem suav tias yog qhov ntsuas qhov ntsuas kom raug. Piv txwv li, 1, 000 ohm resistor nrog 10 feem pua kev lees paub tseem pom tau tias yog qhov raug yog tias nws ntsuas tsis pub tsawg dua 900 ohms thiab tsis ntau dua 1, 100 ohms
Kauj Ruam 5. Npaj digital multimeter (DMM) los ntsuas tus tiv thaiv
DMMs muaj nyob ntawm cov khoom siv hluav taws xob thiab khw muag khoom nyiam.
- Xyuas kom meej tias DMM los txog thiab tsis qhia tias muaj roj teeb tsawg.
- Teem qhov ntsuas ntsuas ntawm DMM rau qhov teeb tsa tom ntej siab dua qhov xav tau tus nqi tiv thaiv. Piv txwv li, yog tias DMM tuaj yeem teeb tsa nplai uas yog sib npaug ntawm 10 thiab tus tiv thaiv tus cim ua 840 ohms yuav tsum ntsuas, teeb DMM rau 1, 000 ohm nplai.
Kauj Ruam 6. Ntsuas qhov tsis kam
Txuas 2 tus coj ntawm DMM mus rau 2 ceg ntawm tus tiv thaiv. Cov neeg tiv taus tsis muaj qhov sib txawv, yog li nws tsis muaj teeb meem twg yog DMM cov hlau lead txuas nrog rau tus tiv thaiv ceg.
Kauj Ruam 7. Txiav txim siab qhov tseeb ntawm cov resistor
Nyeem qhov tshwm sim pom ntawm lub multimeter. Hauv kev txiav txim siab seb puas yog lossis tsis yog tus tiv thaiv nyob hauv thaj tsam tso cai rau tus neeg tawm tsam, tsis txhob hnov qab coj tus neeg tiv taus rau hauv tus lej.
Kauj Ruam 8. Txuas tus resistor uas muab nyeem kom raug
Txuas nws mus rau hauv Circuit Court los ntawm nias nws rov qab rau hauv qhov chaw yog tias koj rub nws dawb nrog koj cov ntiv tes. Yog tias qhov sib koom ua ke yuav tsum tau yaj thiab cov neeg tawm tsam yuav tsum tau txuas nrog siv cov pliers, yaj cov kab laug sab nrog cov hlau txuas thiab siv rab koob lub qhov ntswg los thawb tus tiv thaiv rov qab rau hauv qhov chaw.
Kauj Ruam 9. Hloov tus tiv thaiv uas ntsuas sab nraud ntawm qhov muaj txiaj ntsig ntau
Pov tseg qhov qub resistor. Resistors muaj nyob hauv khw muag khoom hluav taws xob thiab khw muag khoom nyiam. Nco ntsoov tias kev hloov pauv qhov ua haujlwm tsis zoo yuav tsis tas kho qhov teeb meem, yog tias tus tiv thaiv tsis ua tiav qhov qub ntawm qhov teeb meem yuav tsum tau nrhiav lwm qhov hauv Circuit Court.
