Yuav ua li cas yog 50 milliamps zoo li ntawm ib tug multimeter? piav qhia

Multimeter qhia 50 milliamps li 0.05 amps ntawm qhov screen. Yog koj nug li cas? Nyob nrog peb vim tias, nyob rau hauv cov ntawv blog no, peb yuav saib zoo li cas 50 milliamps zoo li ntawm ib qho multimeter!

Multimeter yog dab tsi thiab nws ua dab tsi?

Multimeter yog ib qho cuab yeej uas ntsuas ntau yam khoom hluav taws xob, suav nrog qhov voltage, tam sim no thiab tsis kam. Nws tuaj yeem siv los kuaj cov roj teeb, xaim thiab lwm yam khoom siv hluav taws xob.

Multimeters feem ntau muaj ntau qhov kev ntsuas hluav taws xob thiab kev ntsuas tam sim no, nrog rau ntau qhov kev ntsuas sib txawv. Lawv kuj tuaj yeem siv los ntsuas cov capacitors thiab diodes.

Multimeter yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob. Nws tuaj yeem pab koj txheeb xyuas qhov tsis zoo ntawm lub cuab yeej yog tias nws tsis ua haujlwm lossis siv los ua ib feem ntawm koj lub rooj zaum ua haujlwm uas koj siv ntau yam khoom siv hluav taws xob.

Nyob rau hauv luv luv, ib tug multimeter ntsuas voltage, tam sim no thiab kuj. Nws tuaj yeem siv los kuaj cov roj teeb, fuse, thaiv, thiab lwm yam khoom siv hluav taws xob. Niaj hnub no lawv siv cov duab digital uas ua rau nws yooj yim nyeem cov ntsuas.

Multimeters siv cov duab digital uas ua rau lawv yooj yim siv thiab muab kev ntsuas tseeb rau koj, txawm tias tam sim no yog dab tsi. Niaj hnub nimno multimeters kuj tau tsim los ua ergonomic thiab lub teeb yuag yog li lawv yooj yim siv txawm tias koj siv lawv rau ib teev ib zaug.

Yuav ua li cas yog 50 milliamps zoo li ntawm ib tug multimeter?

Thaum koj ntsuas tam sim no nrog multimeter, kev nyeem ntawv yuav nyob hauv amps. 50 milliamps yog sib npaug rau 0.05 amps. Qhov no txhais tau hais tias nyob rau hauv feem ntau multimeters, 50 milliamps nyeem ntawv yuav tshwm sim raws li ib tug me me teev los yog kab ntawm qhov screen.

Thaum ntsuas tam sim no nrog multimeter, qhov ntsuas ntawm lub ntsuas yuav nyob hauv amps. Milliamps yog ib feem ntawm ib lub amp, yog li thaum ntsuas tam sim no yog 10 milliamps lossis qis dua, lub ntsuas yuav qhia tus nqi ntawm 0.01 ntawm qhov ntsuas amp. Qhov no yog vim lub ntsuas ntsuas ntsuas tam sim no hauv amps.

Thaum ntsuas tam sim no nrog lub multimeter, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias lub 'meter' tsuas yog ntsuas txog qee qhov tam sim no.

Qhov siab tshaj plaws tam sim no uas tuaj yeem ntsuas tau los ntawm ntau qhov multimeters yog nyob ib ncig ntawm 10 amps. Yog tias koj ntsuas qhov tam sim no siab dua 10 amps, lub ntsuas yuav qhia tus nqi ntawm 10 ntawm qhov ntsuas amp.

Nkag siab txog amperes, milliamps thiab microamps

Ib qho ampere (A) yog lub hauv paus SI ntawm hluav taws xob tam sim no. Nws yog tus nqi ntawm cov tam sim no uas ntws los ntawm tus neeg xyuas pib thaum siv qhov hluav taws xob ntawm 1 volt. Ib milliamp (mA) yog ib txhiab ntawm ampere, thiab microamp (μA) yog ib lab ntawm ib ampere.

Tam sim no ntws yog ntsuas hauv amperes. Ib milliamp yog ib qho me me ntawm tam sim no, thiab microamp yog qhov tsawg dua tam sim no.

Tam sim no ntws los ntawm ib lub voj voog tuaj yeem ua rau muaj kev phom sij yog tias nws tsis txwv rau qib kev nyab xeeb. Nws yog ib qho tseem ceeb kom nkag siab qhov txawv ntawm amperes, milliamps thiab microamps thaum ua hauj lwm nrog hluav taws xob circuits.

Cov lus ntawm ampere unit

Lub npe thiab lub xeem	Cim	Hloov dua siab tshiab	Piv Txwv:
microamp (microamp)	μA	1 μA = 10-6A	I = 50 μA
milliampere	mA	1 mA = 10-3A	I = 3 mA
ampere (zeeg)	A	-	I = 10 A
kiloampere (kiloampere)	kA	1 kA = 103A	I = 2 kA

Hloov ua lwm yam amps rau microamps (μA)

Tam sim no kuv hauv microamperes (μA) yog sib npaug rau tam sim no kuv hauv amperes (A) muab faib los ntawm 1000000:

I_(μA) = I_(A) / 1000000

Hloov ua lwm yam amps rau milliamps (mA)

Tam sim no kuv hauv milliamperes (mA) yog sib npaug rau tam sim no kuv hauv amperes (A) muab faib los ntawm 1000:

I_(MA) = I_(A) / 1000

Yuav ua li cas siv multimeter los ntsuas tam sim no?

1. ntsaws rau hauv lub multimeter thiab tig nws

2. Kov lub multimeter dub coj mus rau COM chaw nres nkoj (feem ntau yog qhov chaw nres nkoj puag ncig hauv qab)

3. Kov lub multimeter liab ua rau VΩmA chaw nres nkoj (feem ntau yog qhov chaw nres nkoj sab saum toj)

4. Xaiv qhov ntsuas tam sim no los ntawm tig lub dial ntawm lub multimeter kom txog thaum nws phim lub cim rau kev ntsuas tam sim no (qhov no yuav yog kab squiggly)

5. Qhib lub cuab yeej twg koj tab tom sim los ntawm flipping nws hloov lossis ntsaws rau hauv

6. Ntsuas qhov tam sim no los ntawm kev tso cov dub multimeter lead rau ntawm ib qho ntawm cov hlau prongs thiab kov cov liab multimeter lead mus rau lwm cov hlau prong.
