Yuav txiav txim qhov zoo ntawm DC tam sim no theem (DCA) li cas?
Yog tias muaj qhov paub tam sim no, nkag ncaj qha rau hauv qhov tam sim no. Yog tsis yog, tsis muaj teeb meem. Tsuas yog input qhov voltage nyob rau hauv lub tam sim no ntau yam. Yog tias nws yog 1, hloov nws mus rau qhov qis qis kom txog thaum tus nqi siv tau tshwm. Thov ua tib zoo mloog cov ntsiab lus hauv qab no:
A, Thov tsis txhob nkag siab qhov hluav taws xob ntau dhau kom tsis txhob ua rau lub ntsuas hluav taws xob puas vim yog qhov tam sim no ntau dhau. Cov khoom siv feem ntau siv rau kev tawm tswv yim suav nrog cov roj teeb tsis tu ncua, xws li No. 5, No. 7, thiab lwm yam;
B, Thaum ntsuas qhov tam sim no ntawm qhov hluav taws xob input voltage, vim qhov me me tsis kam (load) ntawm lub ntsuas hluav taws xob sab hauv, yog tias cov tswv yim ntev dhau lawm, nws yuav ua rau lub hauv paus puas. Yog li, nws raug pom zoo kom tsis pub tshaj 5 vib nas this rau ib qho kev tawm tswv yim;
C, Kev sib raug zoo ntawm txhua qhov siab thiab qis, qhov sib txuas, feem ntau yog 10 zaug.
Yuav ua li cas txiav txim qhov zoo ntawm capacitance theem (CAP)?
Feem ntau, nws yog nrhiav lub capacitor nrog tus nqi paub thiab ncaj qha ntxig rau kev ntsuas. Cov txiaj ntsig pom ntawm txhua qhov yuav tsum yog nyob rau hauv 10 fold piv kev sib raug zoo; Thaum kuaj, siv cov hlau capacitors zoo nrog lub peev xwm ruaj khov thiab raug siab. Nws tsis pom zoo kom siv electrolytic capacitors rau kev kuaj vim tias lawv muaj kev ruaj ntseg tsis zoo thiab raug.
Lub hauv paus ntsiab lus ua haujlwm ntawm digital multimeter yog dab tsi Lub hauv paus Circuit Court ntawm digital multimeter yog lub ntsuas hluav taws xob lub taub hau, uas ua haujlwm yooj yim ntawm quantifying lub input DC voltage (analog kom muaj nuj nqis) thiab outputting; Lwm cov haujlwm feem ntau xav tau qhov sib ntxiv ntawm sab nraud circuits. PS: Niaj hnub no, kev koom ua ke ntawm multimeter chips yog nce, thiab tus naj npawb ntawm peripheral circuits yog tsawg. Qhov no muaj ob qho zoo thiab qhov tsis zoo. Qhov zoo: Kev sib koom ua ke siab, yooj yim sab nraud circuits, thiab tsawg dua qhov tsis zoo los ntawm cov teeb meem zoo; Disadvantages: Thaum lub nti tawg lawm, tus nqi hloov pauv siab thiab teeb meem. Qee zaum, txawm tias tus nqi hloov lub nti tuaj yeem siv los yuav lwm lub cuab yeej, yog li feem ntau, nws tsuas yog yooj yim los qhia yog tias nws tawg.
