Resistor - isici eziyisisekelo electronics

Resistor - iyona element elula lezifunda umsakazo-electronic, kokuba impahla ukuba simelane egeleza ngokusebenzisa ke kagesi. Igama lalesi ithuluzi livela egameni English simelane, okusho - ukumelana.

I okuzisholo Resistor ukubaluleka ulinganiswa Ohms (Ohms Ohm m?), Ngemva usosayensi umthetho Georg Ohm wathola, owawuthi ukumelana wesifunda yilona ratio voltage ngezifunda zamanje.

Ngo mboni, resistors akhiqizwa nge ezahlukene okuzisholo ukumelana value. Kunezinhlobo ezintathu eziyinhloko yalezi amadivaysi: esinqunyiwe, variable, Trimmers.

Okungaguquki Resistor - ke isigaba eziningi kakhulu izakhi kokuba impedance njalo. On nezindlu thuluzi libhaliwe, okusho Resistor uhlobo, le okuzisholo ukumelana value ekilasini ukunemba, amandla ukushabalalisa, nabanye. Lolu lwazi okubhalwe ngezindlela ezihlukahlukene. Ngakho, ungakwazi ukuthola izinto okuyiwona yonke idatha ezilotshwe usebenzisa umbala esephepheni (anemibala bands transverse ezintathu kuya kweziyisikhombisa). Ukuze ufunde lezi zimiso, kufanele usebenzise ithebula ekhethekile, engatholwa izincwadi noma incazelo lobuchwepheshe salezi zici. Uhlobo ukuqopha yesibili nezinombolo. Nale ndlela ulwazi idluliselwa esebenzisa izimpawu amadijithi. Ngakho, kungenzeka ukuthi 10 Ohm Resistor kumakwe ngale ndlela: MLT 10R. Kusho MLT uhlobo idivayisi.

Variable Resistor - idivayisi kokuba ibanga eqondile ukumelana bokuzisholo. Uma kwenzeka i-elementi enjalo ukhona ngokulungisa ilungu (knob rotary noma isikulufa), okuyothi ungasetha ukumelana edingekayo zedivayisi. Ngo zinsizakuphila kwenani eliyimali kukhonjisiwe alphanumerical ifomu wokugubha - ezikhonjiswe umkhawulo kusuka okungenani kuya esiphezulu ukumelana value. Amadivayisi anjalo kabanzi ukulawula kanye alamu izilungiselelo: njengoba izilawuli ithoni, amazinga, ivolumu, imvamisa Tuning e umsakazo nalezi zinto.

Kusilungisi - idivayisi kokuba ibanga eqondile ukumelana okuzisholo, kodwa ngokungafani kuya eziguquguqukayo, leli banga abangelutho. izakhi okunjalo kabanzi kagesi. Ahloselwe ukulungiswa kanye intuthuko imingcele edingekayo ekuklanyweni umsakazo noma ukunemba kumadivayisi lapho akuvumelekile chitha izici. Bavumela ngokunembile ukusetha ukumelana edingekayo, okuholela soldered ungene ezingadingekile desoldering-njalo resistors njé ukukhetha inani wayefisa.

Ngaphandle nemingcele eziyisisekelo, iyiphi okuthiwa yisinanakazana rezistorasuschestvuet isici - capacitance. Kuyini lokhu kukho? Capacitance yisinanakazana we Resistor ngokuvamile mncane impela futhi ikakhulukazi noma yini ayiphazamiseki. Kuyadingeka ukuba acabangele kuphela ekuklanyweni imishini ephezulu ukucacisa. capacitance ezidlayo likhona phakathi ilungu pin; kuvela ukuthi Resistor parallel soldered capacitor. Futhi, isitsha kungaphinde kwenzeke phakathi Resistor nezingxenye eduze kwe-PCB ne-izingxenye isakhiwo.

Kulesi kafushane i-elementi ezifana Resistor, sigcine, ukwaziswa okwengeziwe kungatholakala e-zezimboni electronics izincwadi.
