To taub Cov Khoom Siv Hluav Taws Xob Siv Hauv Qhov Chaw Muaj Chaw
Tsis ua haujlwm txhua hnub nrog cov khoom siv hluav taws xob feem ntau cov neeg tseem tsis paub txog qhov ua haujlwm ntawm txhua tus neeg cov khoom yog dab tsi. Kev teeb tsa kev lag luam yog qhov xwm txheej ntau tshaj plaws uas koj yuav tsum tau paub txog txhua qhov sib txawv ntawm cov khoom siv hluav taws xob. Hauv qab no koj yuav pom cov ncauj lus kom ntxaws.
resistors
Qhov feem ntau feem ntau rau txhua lub voj voog koj yuav tuaj ntsib nrog yog tus resistor. Ib qho resistor yog ib feem me me uas yog siv los tsim hluav taws xob tiv thaiv hauv Circuit Court. Lub resistor tso cai rau tus nqi tshwj xeeb ntawm kev tawm tsam hauv hluav taws xob hluav taws xob. Lub caij no ntawm Circuit Court tswj qhov ntws ntawm tam sim no thiab txo qhov voltage uas ntws los ntawm. Yog tias tsis siv cov resistors cov khoom siv hluav taws xob uas peb siv niaj hnub no yuav tsis ua haujlwm lossis muaj kev nyab xeeb. Lub resistor qhov zoo ua rau nws tseem ceeb rau kev siv tau ntawm cov khoom siv hluav taws xob.
capacitors
Qhov thib ob feem ntau tivthaiv tom qab lub resistor yog ib tug capacitor. Lub capacitor yog siv los khaws cov nqi hluav taws xob ib ntus muab tus nqi zoo rau kev ua haujlwm ntawm tag nrho cov khoom uas nws siv.
Thaum xav txog yuav ua li cas lub capacitor ua haujlwm xav tias nws yog lub roj teeb. Qhov txawv yog tias lub capacitor tsis tsim cov khoom siv hluav taws xob nws tsuas yog khaws cia rau lawv. Muaj ntau hom capacitor suav nrog cov hauv qab no:
Cua uas feem ntau yog lub capacitor siv hauv xov tooj cua tuning circuits.
Feem ntau siv rau circuits uas yuav tsum tau timer, Mylar yog siv nyob rau hauv moos, lub tswb los yog txee.
Ib qho zoo heev capacitor nyob rau hauv high voltage daim ntaub ntawv yog iav.
Siv los ua lub capacitor hauv kev siv ntau zaus xws li kav hlau txais xov, x-rays thiab MRI tshuab yog ceramic.
diodes
Lub diode yog ib qho khoom siv uas tso cai rau cov hluav taws xob tam sim no ntws mus rau hauv ib qho kev taw qhia. Cov cuab yeej muaj ob qhov kawg hu ua anode thiab cathode. Lub diode tsuas yog ua haujlwm thaum tam sim no ntws los ntawm thiab siv qhov zoo voltage.
transistors
Transistors yog siv los tswj cov hluav taws xob hluav taws xob. Lawv pab hluav taws xob ntws nruab nrab ntawm ob qhov kawg thiab tso cai rau cov khoom siv hluav taws xob kom ua haujlwm zoo. Transistors yog nrov nrog tib neeg raws li nws muaj txiaj ntsig zoo kawg nkaus thaum xav tau los tswj cov hluav taws xob hluav taws xob uas raug xa mus.
Ntau cov khoom siv hluav taws xob ua haujlwm ua ke hauv kev tsim cov khoom siv hluav taws xob suav nrog cov capacitors, resistors, diodes thiab transistors. Lwm cov kev sib xyaw ua ke siv cov khoom siv no thiab. Nws yog ib qho tseem ceeb uas cov ncauj lus kom ntxaws tau dhau mus ua ntej ncav cuag cov neeg faib khoom. Yog tsis khawb los ntawm ib tug neeg cov ntsiab lus ntawm txhua feem thiab nkag siab txog tus nqi ntawm txhua sector ntawm nws tus kheej raws li zoo raws li thaum siv ua ke koj yuav pom koj tus kheej nrog ntau cov lag luam wholesale hluav taws xob tivthaiv distributors.
