Active vs Passive Components
Txhua cov khoom siv hluav taws xob tuaj yeem muab faib ua ob pawg tseem ceeb xws li cov khoom siv nquag thiab tsis muaj zog. Lub categorization yog nyob ntawm cov khoom muaj peev xwm los tsim lub zog rau lub voj voog. Yog tias ib qho khoom siv xa hluav taws xob mus rau hauv Circuit Court, nws yog nyob rau hauv pawg active Cheebtsam. Yog tias cov khoom siv siv lub zog, nws yog hu ua passive element.
Cov Khoom Siv Ua Haujlwm
Txhua yam khoom uas muaj peev xwm muab lub zog nce yog hu ua cov khoom siv. Lawv txhaj lub zog rau lub voj voog, thiab tuaj yeem tswj tau qhov tam sim no (lossis lub zog) ntws hauv Circuit Court. Ib qho hluav taws xob hluav taws xob yuav tsum muaj tsawg kawg ib qho khoom siv ua haujlwm. Qee qhov piv txwv rau cov khoom siv nquag yog roj teeb, lub tshuab nqus tsev, transistor thiab SCR (silicon controlled rectifier / thyristor).
Kev tswj cov dej ntws tam sim no hauv Circuit Court tej zaum yuav pab tau los ntawm lwm qhov me me tam sim no lossis qhov hluav taws xob. Lawv hu ua tam sim no tswj cov cuab yeej (piv txwv li: Bipolar Junction Transistor) thiab cov khoom siv hluav taws xob tswj hluav taws xob (xws li: Field Effect Transistor).
Passive Components
Cov khoom uas tsis tuaj yeem muab lub zog nce rau hauv Circuit Court yog hu ua passive devices. Cov cuab yeej no tsis muaj peev xwm tswj tau qhov tam sim no (zog) ntws hauv Circuit Court thiab xav tau kev pab ntawm cov khoom siv nquag ua haujlwm. Qee qhov piv txwv rau cov khoom siv passive yog cov resistors, inductors thiab capacitors.
Txawm hais tias cov khoom siv passive tsis tuaj yeem nthuav tawm lub teeb liab nrog qhov nce ntau dua ib qho, lawv tuaj yeem muab cov teeb liab los ntawm tus nqi tsawg dua ib qho. Lawv kuj tuaj yeem oscillate, theem hloov thiab lim cov cim. Qee cov khoom siv passive kuj muaj peev xwm khaws tau lub zog (tsim los ntawm cov khoom nquag) thiab tso tawm tom qab. Piv txwv: capacitors thiab inductors.
Dab tsi yog qhov txawv ntawm cov khoom nquag thiab cov khoom siv tsis zoo?
1. Cov khoom siv nquag txhaj lub zog rau lub voj voog, qhov khoom siv passive tsis muaj peev xwm muab lub zog
2. Cov khoom siv nquag muaj peev xwm muab lub zog nce, thiab cov khoom siv passive tsis muaj peev xwm muab lub zog nce.
3. Cov khoom siv nquag tuaj yeem tswj tau qhov tam sim no (zog) ntws hauv Circuit Court, qhov uas cov khoom siv tsis tuaj yeem tswj tau nws.
