Menene ma'anar alamar ampere multimeter?
Abubuwa
A cikin wannan labarin, zamu tattauna ma'anar alamar ammeter akan multimeter da yadda ake amfani da ammeter.
Menene alamar amplifier multimeter ke nufi?
Alamar amplifier multimeter tana da matukar mahimmanci idan kuna son amfani da multimeter daidai. Multimeter kayan aiki ne da ba makawa wanda zai iya taimaka maka a yanayi da yawa. Ana iya amfani da shi don gwada ingancin wayoyi, gwada batura, da gano abubuwan da ke haifar da rashin aiki na da'ira. Koyaya, idan ba ku fahimci duk alamun akan multimeter ba, ba zai taimaka muku da yawa ba.
Babban maƙasudin alamar ƙarawa shine don nuna adadin halin yanzu da ke gudana ta cikin kewaye. Ana iya auna wannan ta hanyar haɗa jagororin multimeter a jeri tare da kewayawa da auna raguwar ƙarfin lantarki a kansu (Dokar Ohm). Naúrar wannan ma'aunin shine volts a kowane ampere (V/A). (1)
Alamar amplifier tana nufin sashin ampere (A), wanda ke auna wutar lantarki da ke gudana ta kewaye. Hakanan za'a iya bayyana wannan ma'aunin a milliamps mA, kiloamps kA ko megaamps MA dangane da girman girman ko ƙarami.
Bayanin na'urar
Ampere ita ce ma'aunin SI. Yana auna adadin wutar lantarki da ke gudana ta maki daya cikin dakika daya. Ɗayan ampere daidai yake da 6.241 x 1018 electrons da ke wucewa ta wani wuri a cikin dakika ɗaya. Wato 1 amp = 6,240,000,000,000,000,000 electrons a sakan daya.
Juriya da ƙarfin lantarki
Resistance yana nufin adawa da kwararar halin yanzu a cikin da'irar lantarki. Ana auna juriya a cikin ohms kuma akwai dangantaka mai sauƙi tsakanin ƙarfin lantarki, halin yanzu da juriya: V = IR. Wannan yana nufin cewa zaku iya lissafin halin yanzu a cikin amps idan kun san ƙarfin lantarki da juriya. Misali, idan akwai 3 volts tare da juriya na 6 ohms, to na yanzu shine 0.5 amperes (3 raba ta 6).
Amplifier masu yawa
- m = milli ko 10^-3
- u = micro ko 10 ^-6
- n = nano ko 10^-9
- p = pico ko 10^-12
- k = kilogram kuma yana nufin "x 1000". Don haka, idan kun ga alamar kA, yana nufin darajar x shine 1000
Akwai wata hanya ta bayyana wutar lantarki. Abubuwan da aka fi amfani da su na tsarin awo sune ampere, ampere (A), da milliamp (mA).
- Formula: I = Q/t inda:
- I = wutar lantarki a cikin amps (A)
- Q= caje a cikin coulombs (C)
- t= tazarar lokaci a cikin dakika (s)
Lissafin da ke ƙasa yana nuna yawancin nau'o'in da aka saba amfani da su da yawa na ampere:
- 1 MΩ = 1,000 Ω = 1 kΩ
- 1 µΩ = 1/1,000 Ω = 0.001 Ω = 1 mΩ
- 1 nΩ = 1/1,000,000 0 Ω = XNUMX
Takaitattun bayanai
Wasu daga cikin madaidaitan taƙaitaccen taƙaitaccen bayani suna nuni ne ga wutar lantarki da za ku iya fuskanta. Su ne:
- mA - milliamp (1/1000 amp)
- uA - microampere (1/1000000 ampere)
- nA - nanoampere (1/1000000000 ampere)
Yadda ake amfani da ammeter?
Ammeters suna auna adadin halin yanzu ko kwararar wutar lantarki a cikin amps. An ƙera Ammeters don haɗawa a jeri tare da kewaye da suke sa ido. Ammeter yana ba da mafi ingancin karatu lokacin da kewaye ke gudana da cikakken nauyi lokacin karantawa.
Ana amfani da Ammeters a aikace-aikace iri-iri na lantarki da na lantarki, galibi a matsayin ɓangare na ƙarin hadaddun kayan aiki kamar multimeters. Don ƙayyade girman girman ammeter da ake buƙata, kuna buƙatar sanin iyakar da ake tsammanin halin yanzu. Mafi girman adadin amps, mafi fadi da girma da waya da ake buƙata don amfani a cikin ammeter. Wannan saboda babban halin yanzu yana haifar da filin maganadisu wanda zai iya tsoma baki tare da karanta ƙananan wayoyi.
Multimeters suna haɗa ayyuka da yawa a cikin na'ura ɗaya, gami da voltmeters da ohmeters, da ammeters; wannan ya sa su zama masu amfani sosai ga aikace-aikace iri-iri. Masu wutar lantarki, injiniyoyin lantarki da sauran ’yan kasuwa ne ke amfani da su.
Dubi wasu labaran mu a kasa.
