Feem ntau hu ua AVO Meter Multimeter los yog Multitester. Ntawm lo lus yuav ua tau ib tug nkag siab ntawm AV ' meter ' yog ib qho khoom siv rau kev ntsuas tam sim no, voltage, ob qho tib si hloov tam sim no (AC) Direct Current (DC) thiab hluav taws xob tsis kam.
Yog li ntawd, dab tsi yog qhov kev siv ntawm multimeter?
A Multimeter yog ib qho khoom siv hluav taws xob, txhua tus kws tshaj lij hluav taws xob thiab cov kws tsim khoom siv dav siv cov khoom siv ntsuas. Multimeter Feem ntau yog siv los ntsuas peb qhov yooj yim hluav taws xob yam ntxwv ntawm voltage, tam sim no thiab tsis kam. Nws tseem tuaj yeem siv los ntsuas kev txuas ntxiv ntawm ob lub ntsiab lus hauv hluav taws xob hluav taws xob.
Tsis tas li ntawd, ob yam dab tsi ua qhov ntsuas ohmmeter? Ib ohmmeter yog ib qho cuab yeej hluav taws xob uas ntsuas hluav taws xob tsis kam (qhov kev tawm tsam muab los ntawm ib yam khoom rau qhov ntws ntawm hluav taws xob tam sim no). Micro- ohmmeters (microhmmeter los yog micro ohmmeter ) ua kom tsis muaj zog kev ntsuas . Megohmmeters (tseem yog lub cim lag luam Megger) ntsuas loj qhov tseem ceeb ntawm kev tiv thaiv.
Yog li ntawd, koj txhais li cas los ntawm multimeter?
A multimeter los yog ib tug multitester, tseem hu ua VOM (volt-ohm-milliammeter), yog ib qho khoom siv hluav taws xob ntsuas uas sib txuas ntau yam kev ntsuas hauv ib chav. Digital multimeters (DMM, DVOM) muaj cov lej tso saib, thiab tseem tuaj yeem pom cov duab kos uas sawv cev rau tus nqi ntsuas.
Dab tsi yog hom multimeter?
Muaj ob qho yooj yim hom multimeters : digital multimeters thiab analog multimeters . Tag nrho cov digital multimeters muaj plaub ntu: ib qho zaub, dial, nyees khawm, thiab input jacks. Multimeters tau muab faib ua plaub pawg: CAT I, CAT II, CAT III, thiab CAT IV.

Dab tsi yog qhov kev txawj ntse ntawm qhov pom kev siv rau?
Spatial peev xwm los yog visuo-spatial muaj peev xwm yog lub peev xwm to taub, laj thawj, thiab nco ntsoov qhov kev sib raug zoo ntawm cov khoom lossis qhov chaw. Visual-spatial peev xwm yog siv rau txhua hnub siv los ntawm kev taw qhia, kev nkag siab lossis kho cov cuab yeej, kev nkag siab lossis kwv yees qhov deb thiab ntsuas, thiab ua haujlwm ntawm kev ua haujlwm
Dab tsi yog kev siv cov saw hlau nuclear siv rau?
Nuclear chain reaction. Nuclear chain reactions yog cov tshuaj tiv thaiv uas tau txais lub zog nuclear, feem ntau los ntawm nuclear fission. Cov kev cuam tshuam ntawm cov saw hlau no yog qhov muab cov chaw tsim hluav taws xob nuclear nrog lub zog uas tom qab ntawd hloov mus ua hluav taws xob siv los ntawm tib neeg
Dab tsi yog cov kev siv ntawm kev sib koom ua ke?
Ib daim ntawv thov tseem ceeb ntawm kev sib koom ua ke yog lawv siv los ua cov catalysts, uas pab hloov cov tshuaj tiv thaiv kab mob. Qee qhov nyuaj hlau catalysts, piv txwv li, ua lub luag haujlwm tseem ceeb hauv kev tsim cov polyethylene thiab polypropylene
Dab tsi yog qhov teeb meem loj tshaj plaws ntawm kev siv cov kev tshawb fawb txog kev sib raug zoo?
Tej yam tsis zoo los yog kev tshawb fawb txog kev sib raug zoo muaj xws li: a. Lawv tsis tuaj yeem siv los tsim kom muaj kev sib raug zoo-thiab-tshuaj los yog kev coj ntawm kev cuam tshuam
Dab tsi yog qhov sib npaug siv los xam tag nrho cov khoom siv hluav taws xob siv?
Cov mis uas txuas lub zog thiab lub zog yog: Zog = Lub Zog x Sijhawm. Chav tsev ntawm lub zog yog joule, lub zog ntawm lub zog yog watt, thiab chav tsev ntawm lub sijhawm yog qhov thib ob
