Thov qhia rau kuv paub yog tias koj muaj lus qhia ntxiv txhawm rau txhim kho kev siv tau ntawm cov cuab yeej tsim qauv no!

Kauj ruam 1: Tom qab

Daim ntawv thov web no tau tsim tawm ntawm qhov xav tau. Muaj ntau ntau yam kev sib txawv uas kuv tsim uas xav tau tshwj xeeb heev resistor lossis capacitor. Ntau zaus, Kuv tsis muaj tus tiv thaiv lossis tus capacitor nrog tus nqi tshwj xeeb ntawd. Qee zaum lawv tsis txawm ua ib feem nrog tus nqi tshwj xeeb ntawd! Hloov chaw lossis tso tseg rau qee yam uas tsawg dua li qhov zoo, Kuv txiav txim siab sau ib qhov program los saib txhua qhov ua tau ntawm cov tshuaj tiv thaiv (txhua qhov muaj peev xwm ua tau thiab seb lawv nyob hauv koob lossis sib luag) thiab rov qab ua ke zoo tshaj plaws.

Thaum tsim cov phiaj xwm rau kuv lub cev ua ib feem ntawm kuv Kev Sib Tw ntawm Cov Pab Pawg Qhia Ntawv, Kuv yuav tsum tau sim tes xam qhov zoo tshaj plaws ua ke ntawm cov khoom siv hluav taws xob kom ua tiav qhov tshwj xeeb. Cov txheej txheem no tsis txaus ntseeg kawg thiab thaum kawg kuv tsuas yog tso tseg thiab mus nrog cov khoom sib txuas ua ke uas ua rau muaj ntau npaum li cas ntawm lub suab nrov. Tam sim no nrog daim ntawv thov web no, Kuv tuaj yeem tsim kuv lub cev rau qhov tshwj xeeb zaus thiab qhib nws mus rau cov ntawv sau ntawm cov keyboard! Cov kab zauv hauv qab no yog siv los laij cov zaus tshwj xeeb thiab tau tham hauv lwm qhov Kev Qhia Ua Haujlwm.

f = 1 / (0.693 × C × (R1 + 2 × R2))

Siv qhov kev ua zauv no qhov twg R1 = 100 kOhm thiab R2 = 10 kOhm, Kuv suav tias 27.33 nF capacitor yuav tsim A4 ntawv (zaus 440 Hz). Siv kuv qhov program, Kuv muaj peev xwm los xam qhov muaj peev xwm sib npaug hauv.001 nF (ntau tsawg dua qhov ua siab ntev ntawm tus qauv ntsuas) uas kuv tuaj yeem tsim siv cov capacitors Kuv twb tau pw ib puag ncig. Cov txiaj ntsig tau tshwm sim thiab teeb tsa tau piav qhia hauv qab no. Tam sim no kuv muaj peev xwm ua tau ntau dua thiab muaj txiaj ntsig zoo qhib kuv lub cev rau qhov tseeb zaus ntawm cov ntawv sau tseg. Kuv vam tias kuv tau ua qhov no los pib nrog. Kuv zaj nkauj demo ntawm lub cev tej zaum yuav muaj suab zoo dua.

Tus nqi ze tshaj: 27.329 nF Qhov txawv: 0.001 nFCapacitor Kev teeb tsa: C0 = 0.068 nF || C1 = 30 nF + C2 = 300 nF

Resistor Capacitor Sib npaug sib npaug

Rau kev siv, hauv qab no yog qhov sib npaug sib npaug rau kev sib txuas cov resistors thiab cov capacitors hauv Circuit Court.

• Resistors hauv series (R1 + R2): Req = R1 + R2
• Resistors nyob rau hauv parallel (R1 || R2): Req = 1/(1/R1 + 1/R2)
• Capacitors hauv series (C1 + C2): Ceq = 1/(1/C1 + 1/C2)
• Capacitors nyob rau hauv parallel (C1 || C2): Ceq = C1 + C2

Kauj ruam 2: Cov tswv yim

Muaj 4 lub tswv yim koj yuav tsum tau muab:

1. Txawm hais tias koj tab tom suav tus nqi rau tus tiv thaiv lossis tus capacitor.
2. Lub hom phiaj tsis kam lossis tus nqi peev txheej thiab chav nyob.
3. Tus naj npawb siab tshaj plaws ntawm cov khoom koj xav siv kom ua tiav lub hom phiaj tus nqi (piv txwv li kuv tsis xav siv ntau dua 3 tus tiv thaiv kom ua tiav kuv lub hom phiaj tiv taus tus nqi).
4. Cov npe ntawm qhov tseem ceeb rau cov resistors/capacitors koj tam sim no muaj. Cov txiaj ntsig no yuav tsum nyob hauv tib chav raws li koj lub hom phiaj (piv txwv li yog tias koj lub hom phiaj tus nqi yog 110 nF, tag nrho koj cov txiaj ntsig yuav tsum tau muab hauv nF).

Kauj Ruam 3: Qhov tshwm sim

Koj yuav tau txais 3 qhov txiaj ntsig rau koj qhov txiaj ntsig:

1. Tus nqi ze tshaj - qhov muaj peev xwm tiv taus/muaj peev xwm tshaj plaws uas koj tuaj yeem ua tiav nrog koj qhov ntsuas.
2. Qhov sib txawv - nyob deb li cas ntawm koj tus nqi ze tshaj yog los ntawm koj lub hom phiaj.
3. Resistor/Capacitor Configuration - cov npe ntawm qhov tseem ceeb ntawm cov resistors/capacitors siv thiab lawv teeb tsa.

Kauj Ruam 4: Nkag Siab Koj Li Qhov tshwm sim

Cov txheej txheem teeb tsa siv tus qauv cim. "+" txhais tau tias cov khoom sib xyaw ua ke thiab "||" txhais tau tias cov khoom sib dhos ua ke. Cov neeg ua haujlwm muaj qhov sib npaug ua ntej thiab sab laug-rau-txoj cai koom nrog lub ntsiab lus koj pab pawg ua ke pib los ntawm sab laug thiab txav mus rau sab xis.

Piv txwv li, ua tibzoo saib cov txiaj ntsig hauv qab no:

Resistor Configuration: R0 = 15 Ohms + R1 = 470 Ohms || R2 = 3300 Ohms + R3 = 15000 Ohms

Yog tias koj ua raws cov lus qhia tau hais los saum toj no, koj tuaj yeem pom tias qhov no zoo ib yam li cov kab zauv hauv qab no thiab cov duab saum toj no.

((R0+R1) || R2)+R3
