Thaum koj pom cov infinite kuj ntawm lub multimeter digital, nws txhais tau hais tias tsis muaj hluav taws xob tam sim no ntws los ntawm cov khoom koj ntsuas. Yog li ntawd, unlimited tsis kam txhais tau hais tias lub multimeter tau ntsuas ntau heev tsis kam tias tsis muaj ntws tawm.

Ib yam li ntawd, kev nyeem ntawv tsis kawg ohm yog dab tsi?

Infinity ohms - Qhov no yog qhov ohmmeter nyeem thaum muab tso rau ntawm qhov qhib Circuit Court. Nyob rau hauv ib qho analog meter infinity ua ohms yog thaum rab koob tsis txav txhua qhov thiab ntawm lub ntsuas ntsuas digital infinity ua ohms yog 1.

Tsis tas li ntawd, dab tsi suav tias yog kev tiv thaiv siab? Siab hluav taws xob tsis kam yog qhov kev tawm tsam rau tam sim no ntws hauv ib lub voj voog. A siab hluav taws xob tsis kam ntawm tus neeg xyuas pib hluav taws xob yog qhov cuam tshuam rau qhov ntws ntawm cov hluav taws xob tam sim no los ntawm tus neeg xyuas pib; inverse ntsuas yog hu ua hluav taws xob conductance. SI unit of electronics tsis kam yog ohm (O).

Yog li ntawd, dab tsi yog qhov kev nyeem ntawv zoo?

Cov tsis kam ntawm ib qho kev tivthaiv tuaj yeem nyob ntawm ohms (1 ohm) mus rau megaohms (1, 000, 000 ohms). Yuav kom tau txais qhov tseeb nyeem ntawv ntawm tsis kam Koj yuav tsum teem lub multimeter rau qhov zoo rau koj cov khoom. Yog tias koj tsis paub qhov ntau, pib nrog qhov nruab nrab qhov chaw, feem ntau 20 kilo-ohms (kΩ).

Puas yog Ol txhais tau tias tsis muaj kev tawm tsam?

Infinite kuj (qhib Circuit Court) yog nyeem raws li OL ” ntawm Fluke meter zaub, thiab txhais tau tias tus tsis kam yog ntau tshaj qhov ntsuas tau.

Dab tsi yog qhov txawv ntawm kev nyeem qhov tob micrometer thiab sab nraud micrometer?

Qhov kev faib tawm no muaj peb qhov kev faib: sab hauv, sab nraud, thiab qhov tob micrometers. Sab hauv yog tsim los ntsuas qhov ntev ntawm ib qho khoom. Sab nraud yog ntsuas sab nraud txoj kab uas hla, lub thickness ntawm ib yam dab tsi, thiab ntev. Qhov tob yog ntsuas qhov tob ntawm qhov

Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?

Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua

Dab tsi yog qhov kev sib raug zoo ntawm kev ua lej ntawm qhov kev nyuaj siab khov kho thiab Mollality?

Kev nyuaj siab qhov chaw khov kho yog cov cuab yeej sib koom ua ke pom hauv cov kev daws teeb meem uas tshwm sim los ntawm kev qhia txog cov kuab tshuaj molecules rau cov kuab tshuaj. Cov ntsiab lus khov ntawm cov kev daws yog tag nrho qis dua li cov kuab tshuaj ntshiab thiab yog ncaj qha proportional rau molality ntawm cov kuab tshuaj

Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?

Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
