Yog tias koj tsis paub meej txog tam sim no, pib nrog 10 ampere davhlau ya nyob twg kom txog thaum koj paub tseeb tias tam sim no tsawg dua 300 milliamperes.
Kauj Ruam 2. Teeb lub multimeter los ntsuas qhov tam sim no
Hom no tau cim nrog tsab ntawv A.
Kauj Ruam 3. Tua lub hwj chim rau hauv Circuit
Kauj Ruam 4. Txiav qhov Circuit Court
Txhawm rau ntsuas tam sim no, koj yuav tsum txuas lub multimeter hauv koob. Muab ib qho kev sojntsuam rau ntawm txhua qhov kawg ntawm qhov thooj, ua tib zoo saib xyuas qhov polarity (qhov kev sojntsuam dub ntawm tus ncej tsis zoo, sojntsuam liab ntawm tus ncej zoo).
Kauj Ruam 5. Qhib lub hwj chim
Qhov tam sim no yuav hla lub Circuit Court, nkag mus rau qhov kev sojntsuam liab thiab hla lub multimeter, tom qab ntawd tawm ntawm qhov kev sojntsuam dub thiab nkag mus rau hauv Circuit Court dua.
Kauj Ruam 6. Nyeem cov lej tso tawm, nco ntsoov tias koj ntsuas hauv amperes lossis milliamperes
Koj tuaj yeem siv lub ntsej muag tuav tuav yog tias koj xav tau.
Txoj Kev 3 ntawm 5: Ntsuas Teeb Meem
Kauj Ruam 1. Txuas lub multimeter rau hauv Circuit Court
Ntxig qhov kev sojntsuam dub rau hauv lub davhlau ya nyob twg thiab qhov kev sojntsuam liab rau hauv qhov ntsuas hluav taws xob thiab qhov ntsuas tsis kam. Lub davhlau ya nyob twg no tseem tuaj yeem siv los tshuaj xyuas cov diodes.
Kauj Ruam 2. Tig lub pob qhov rooj kom hloov kho qhov tsis kam
Hom no tau qhia los ntawm Greek tsab ntawv Omega, uas sawv rau ohm, chav ntsuas ntawm kev tiv thaiv.
Kauj Ruam 3. Tua lub hwj chim rau hauv Circuit
Kauj Ruam 4. Tshem tus resistor uas koj xav ntsuas
Yog tias koj tso tus resistor hauv Circuit Court, qhov ntsuas ntsuas yuav tsis raug.
Kauj Ruam 5. Kov lub taub hau sojntsuam mus rau txhua qhov kawg ntawm tus tiv thaiv
Kauj Ruam 6. Nyeem cov lej tso tawm, ua tib zoo mloog cov koog
Kev ntsuas ntawm 10 tuaj yeem qhia txog 10 ohms, 10 kilo-ohms lossis 10 mega-ohms.
Txoj Kev 4 ntawm 5: Txheeb Xyuas Diodes
Kauj Ruam 1. Ntxig qhov kev sojntsuam dub rau hauv lub davhlau ya nyob twg thiab qhov kev sojntsuam liab rau hauv lub davhlau ya nyob twg txhawm rau ntsuas kev tiv thaiv, qhov hluav taws xob, lossis kos diodes
Kauj Ruam 2. Siv lub pob tes taw los xaiv lub diode kos ua haujlwm

Muab qhov kev sojntsuam liab tso rau ntawm tus ncej zoo ntawm tus diode thiab cov sojntsuam dub ntawm tus ncej tsis zoo. Yog tias koj tau txais qhov ntsuas ntawm tsawg dua 1 tab sis ntau dua 0, kev tsis ncaj ncees rau tom ntej yog qhov zoo.
Kauj Ruam 5. Tig tus neeg tshawb nrhiav dua txhawm rau txheeb xyuas qhov tsis ncaj ncees
Yog tias qhov ntsuas ntsuas pom "OL" (ntau dhau), qhov no qhia txog qhov rov qab tsis ncaj ncees yog nyob zoo.
Kauj Ruam 6. Kev nyeem ntawv ntawm "OL" lossis 0 thaum txheeb xyuas qhov tsis ncaj ncees, thiab 0 thaum txheeb xyuas qhov tsis zoo rov qab qhia tias tsis zoo rau lub cev
Qee qhov ntsuas ntsuas yuav nyem thaum ntsuas qhov ntsuas tsawg dua 1. Qhov no tsis tas yuav qhia tias lub diode nyob hauv qhov xwm txheej zoo, vim qhov ua tsis raug diode tseem yuav ua rau pom lub teeb
Txoj Kev 5 ntawm 5: Ntsuas Kev Txuas Mus Ntxiv
Kauj Ruam 1. Ntxig qhov kev sojntsuam dub rau hauv lub davhlau ya nyob twg thiab qhov kev sojntsuam liab rau hauv qhov ntsuas hluav taws xob thiab tiv taus lub davhlau ya nyob twg
Kauj Ruam 2. Teeb lub multimeter rau tib qhov chaw siv los tshuaj xyuas lub diode
