Yuav ua li cas thiaj txiav txim seb DC tam sim no (DCA) yog qhov zoo lossis tsis zoo?
Yog tias muaj cov lus paub tam sim no, qhia ncaj qha rau hauv hom tam sim no. Yog tias tsis yog, nws tsis ua li cas. Tsuas tawm cov tswv yim ntawm voltage hauv hom tam sim no. Yog tias nws tawm mus rau 1, hloov nws mus rau qhov qis dua hom kom txog thaum tus nqi siv tau tshwm sim. Thov saib xyuas cov ntsiab lus hauv qab no:
A. Thov tsis txhob tawm cov ntaub ntawv ntau dhau voltage kom tsis txhob ua rau muaj kev puas tsuaj vim yog ntev tam sim no. Cov peev txheej uas tuaj yeem tawm tswv yim suav nrog cov roj teeb tsis tu ncua xws li No.5, No.7, thiab lwm yam;
B. Thaum ntsuas qhov ntsuas hluav taws xob tam sim no (thauj khoom me me (thauj khoom) ntawm sab hauv kev tawm tsam, yog tias cov tswv yim ntev dhau, nws yuav ua rau qhov chaw. Yog li ntawd, ib qho tswv yim ib leeg yuav tsum tsis pub dhau 5 vib nas this ntau li ntau tau;
C. Kev sib raug zoo ntawm cov siab sib txawv thiab tsawg dua li ntau, feem ntau yog li, feem ntau yog 10 zaug.
Yuav ua li cas txiav txim siab qhov zoo ntawm lub capacitor theem (cap)?
Feem ntau, lub capacitor nrog tus muaj npe paub yog pom thiab ntxig ncaj qha rau kev ntsuas. Cov txiaj ntsig tshwm sim ntawm txhua qhov yuav tsum nyob hauv 10 zaug ib zaug sib txheeb; Nws yog qhov zoo tshaj plaws kom siv cov hlau capacitors nrog lub peev xwm ruaj khov thiab qhov tseeb ntawm thaum kuaj. Nws tsis pom zoo kom siv electrolytic capacitors rau kev xeem, raws li lawv cov kev ruaj khov thiab qhov tseeb tsis zoo.
Dab tsi yog qhov tseem ceeb ua haujlwm ntawm cov digital multimeter?
Teb: Qhov yooj yim Circuit Court ntawm cov digital potalimeter yog ib qho kev ntsuas cov ntaub ntawv DC voltage (analog) thiab tawm nws; Lwm yam haujlwm feem ntau yuav tsum muaj qhov sib ntxiv ntawm cov voj voog sab nraud. PS: Tam sim no, kev sib koom ua ke ntawm kev sib xyaw ua ke yog nce ntxiv, thiab qhov kev sib tw ntawm cov neeg tsawg thiab tsawg dua, uas muaj ob qho tib si thiab qhov tsis zoo. Cov txiaj ntsig zoo: Kev sib koom ua ke, yooj yim sab nraud ncig, thiab tsawg dua qhov ua tsis tiav tshwm sim los ntawm cov teeb meem muaj kev tiv thaiv zoo; Qhov tsis zoo: Thaum lub nti tawg cia, tus nqi hloov tau yog siab thiab teeb meem. Qee zaum, cov nyiaj tau siv ntawm kev hloov ib qho nti tuaj yeem siv los yuav lwm qhov ntsuas, yog li feem ntau nws yuav tsum tau txhuam.
