Los ntawm: Electronics 101, tej zaum yuav nyiag cov ntaub ntawv qhia yav tom ntej los ntawm qhov no
Thaum kawg, cov capacitors khaws cov nqi. Muaj ntau yam koj ua nrog cov capacitors.
Cov capacitors mus zoo heev hauv cov lim dej hluav taws xob - los lim cov zaus uas koj tsis xav tau.
Ib lub lim dej qis dhau - cov zaus qis tshwm sim ntawm qhov tso zis, cov zaus siab raug txiav tawm.
Ib lub lim dej siab dhau - cov zaus siab tshwm sim ntawm qhov tso zis, cov zaus qis raug txiav tawm.
Ua ke nrog lub inductor, lawv ua ib lub voj voog resonator uas tuaj yeem txiav tawm tsuas yog ib qho nqaim ntawm cov zaus lossis txawm tias ua kom nrov dua ib qho zaus.
Ib lub lim dej band-pass uas tso cai rau tsuas yog cov zaus tshwj xeeb kom dhau.
Cov capacitors feem ntau siv los pab kom lub zog fais fab ruaj khov - txij li thaum lawv tsim ib qho shunt rau AC tab sis tawm hauv DC ib leeg, yog tias koj xav tau lub zog fais fab ruaj khov koj yuav siv cov capacitors los shunt tawm suab nrov, tawm hauv qhov hluav taws xob DC zoo ruaj khov ntawm qhov tso zis.
Qhov kev teb ib ntus ntawm RC Circuit kuj tseem muaj txiaj ntsig zoo rau lub sijhawm.
Kev teb ib ntus ntawm RC circuit
Vim tias nws siv sijhawm kwv yees tau kom ncav cuag qhov voltage tshwj xeeb, nws tuaj yeem siv los teem sijhawm hloov hluav taws xob.
Lub sijhawm qhib thiab lub sijhawm tawm yog teeb tsa los ntawm lub capacitor thiab ob lub resistors hauv lub voj voog sijhawm qhia saum toj no.
Dua li ntawd, vim lawv khaws cov nqi, lawv tuaj yeem siv ua ib feem ntawm lub kaw lus los hloov AC mus rau DC.
Yog tsis siv lub capacitor, es tsis txhob ua DC rippled, nws zoo li nthwv dej sine nrog qhov hauv qab tig mus rau saum.
Qhov ntawd tsuas yog ib qho kev kuaj me me xwb. Lawv ua ntau yam, suav nrog kev sib txawv thiab kev koom ua ke (calculus functions), decouple biased circuits, hloov voltage theem kom them lub zog, thiab tuav lub charge rau kev siv ib ntus.
Thiab tom qab ntawd muaj txhua yam uas koj tsis xav tau capacitance rau, tab sis yuav tsum tau daws nrog vim tias capacitance yog ib yam khoom siv, tsis yog ib yam dab tsi uas tsuas muaj nyob rau ntawm cov khoom siv uas teev nws. Zoo li kev sib tham hla lub teeb liab, kev ua si nrog cov tswv yim thiab cov zis impedance, ntxiv suab nrov, ua rau muaj kev co acoustic, thiab lwm yam.
