Resistor - element a aasaasiga ah ee korantada

Resistor - waa element ugu fudud ee wareeggeedii radio-electronic, isagoo hantida in ay iska caabin ah dal dhex hadda korontada. Magaca qalab this ka timaadaa ereyga Ingiriisiga ah ee iska caabin ah, taas oo macnaheedu yahay - iska caabin ah.

The qiimaha resistor magacaaban qiyaasay in Ohms (Ohms Ohm m?), Ka dib cilmiga sharciga Georg Ohm ayaa helay, sida uu sheegay oo iska caabin ah circuit waa ratio ee danab si circuit hadda.

In warshadaha, resistors waxaa lagu soo saaray iyadoo qiimaha caabin magacaaban kala duwan. Waxaa jira saddex nooc oo waaweyn oo qalabka: go'an, variable, laambadihii.

resistor go'an - waa dabaqadda ugu badan ee canaasiirta isagoo impedance joogto ah. On guryaha qalab noocan oo kale ah waxaa ku tilmaamay, taasoo la micno ah nooca resistor, qiimaha caabiga ku magacaaban fasalka saxnimada, awood dhereg badan, iyo kuwo kale. Macluumaadkan waxaa encoded siyaabo kala duwan. Sidaas, waxaad ka heli kartaa alaabta kaas oo dhammaan xogta diiwaan isticmaalaya koodh midabka (saddex ilaa toddoba guutooyin transverse midab). Si aad u akhriso qiimayaashan, waa in aad isticmaasho miis gaar ah, kaas oo laga heli karaa buugaagta la soo xigto ama description farsamo ah ah walxahaasi. Nooca labaad ee wax lagu qoro waa alphanumeric. Iyadoo habkan macluumaadka loo kala qaado by yahay calaamadaha iyo lambar. Sidaas darteed, 10 Ohm resistor laga yaabaa in lagu calaamadeeyay sida soo socota: MLT 10R. Waxaa loola jeedaa aalad nooca MLT.

resistor variable - qalab isagoo kala duwan oo gaar ah oo iska caabin ku magacaaban. Xaaladdan oo element oo caynkaas ah oo jirta qabsado xubin (buro Rotary ama fur), kaas oo ay kuu sameeyaan iska caabin ah loo baahan yahay ee qalabka. In qalabka sida qiimaha magacaaban tilmaamay in sixitaanka foomka alphanumerical ah - muujinaysaa ka ugu yar qiimaha iska caabin ah ugu badnaan xad. aaladaha noocan oo kale ah waxaa si weyn loo isticmaalaa in lagu xakameeyo iyo qaylo goobaha, sida koontaroolada midab, heerarka, mugga, daafigaw soo noqnoqoshada ee raadiyaha qalab qaata.

Trimmer - qalab isagoo kala duwan oo gaar ah oo iska caabin ku magacaaban, laakiin in la barbardhigo ah doorsoomayaasha, this kala duwan oo aan qiimo lahayn. xubno noocan oo kale ah hubkaas ayaa loo isticmaalaa in wareeggeedii electronic. Waxay waxaa loogu talagalay habayn iyo dib uhabaynta-beegyada uu u baahan yahay in design ah ee qalabka raadiyaha ama sax meesha looma oggola sifooyinka kala firdhiso. Waxay u ogolaadaan in ay si hufan u dhigay iska caabin ah loo baahan yahay, taasoo keentay soldered gal resistors desoldering-joogta ah loo baahnayn magacaaban for xulashada qiimaha la doonayo.

Ka sokow ku soo koobin aasaasiga ah, wax kasta oo wax-u dabeecad rezistorasuschestvuet dulinka - capacitance. Waa maxay Doorashadan? capacitance The dulinka resistor sida caadiga ah waa kuwo yar yar iyo gaar ahaan wax ma u saameeyeen. Waxaa lagama maarmaan ah inay tixgeliyaan oo kaliya in design ah ee qalabka-sax sare. capacitance Baadiyaha joogo dhexeeya xubin ka pin ah; waxaa soo baxday in resistor ka barbar soldered capacitor. Sidoo kale, weelka sidoo kale laga yaabaa inuu dhaco ka dhexeeya resistor iyo qaybo ka ku xiga ee PCB ah iyo qaybo ka mid ah dhismaha.

In guudmar kooban oo ku saabsan this element ah sida resistor ah, waxaan aakhirka, macluumaad dheeraad ah waxaa laga heli karaa in laga barto korantada warshadaha.
