Maxay ka dhigan tahay calaamadda ampere multimeter?
Tusmo
Maqaalkan, waxaan kaga hadli doonaa macnaha calaamadda ammeter-ka ee multimeterka iyo sida loo isticmaalo ammeterka.
Waa maxay macnaha calaamadda cod-weyneeye-weynuhu?
Calaamadda cod-weyneeye-badane waa mid aad muhiim u ah haddii aad rabto inaad si sax ah u isticmaasho multimeterka. Multimeter-ku waa qalab aan laga maarmi karin oo ku caawin kara xaalado badan. Waxaa loo isticmaali karaa in lagu tijaabiyo tayada fiilooyinka, tijaabinta baytariyada, iyo in la ogaado qaybaha keenaya in wareeggaagu xumaado. Si kastaba ha ahaatee, haddii aadan fahmin dhammaan calaamadaha ku yaal multimeterka, wax badan kuma caawin doono.
Ujeedada ugu weyn ee calaamada cod-weyneeye waa in la tilmaamo qadarka hadda socda ee wareegga. Tan waxa lagu cabbiri karaa iyadoo la isku xidho hagayaasha mitirka badan ee taxanaha ah wareegga iyo cabbiraadda hoos u dhaca korantada ee dhexdooda (Sharciga Ohm). Halbeegga cabbirkan waa volts per ampere (V/A). (1)
Astaanta cod-weyneeye waxa ay tilmaamaysaa halbeegga ampere (A), kaas oo cabbiraya korantada ku socota wareegga. Cabbirkan waxa kale oo lagu muujin karaa milliamps mA, kiloamps kA ama megaamps MA iyadoo ku xidhan inta uu le'eg yahay ama yar yahay qiimuhu.
Sharaxaada aaladda
Ampere waa halbeegga SI ee cabbirka. Waxa ay cabbirtaa xadiga korantada ee ku socota hal dhibic hal ilbiriqsi. Hal ampere waxa ay la mid tahay 6.241 x 1018 elektaroonig ah oo dhex maraya meel cayiman hal ilbiriqsi gudaheed. Si kale haddii loo dhigo, 1 amp = 6,240,000,000,000,000,000 electrons ilbiriqsikii.
Iska caabin iyo danab
Iska caabintu waxaa loola jeedaa ka soo horjeeda socodka hadda ee wareegga korantada. Iska caabinta waxaa lagu qiyaasaa ohms waxaana jira xiriir fudud oo u dhexeeya danab, hadda iyo caabbinta: V = IR. Tani waxay ka dhigan tahay in aad ku xisaabin karto hadda ku jira amps haddii aad taqaanid tamarta iyo caabbinta. Tusaale ahaan, haddii ay jiraan 3 volts oo leh iska caabin ah 6 ohms, markaa hadda waa 0.5 amperes (3 loo qaybiyay 6).
Amplifier-ka badan
- m = milli ama 10 ^-3
- u = micro ama 10 ^ -6
- n = nano ama 10^-9
- p = pico ama 10^-12
- k = kiiloogaraam oo macnaheedu yahay "x 1000". Marka, haddii aad aragto calaamadda kA, waxay la macno tahay x qiimaha waa 1000
Waxaa jirta hab kale oo lagu muujiyo korantada. Unugyada inta badan la isticmaalo ee nidaamka mitirka waa ampere, ampere (A), iyo milliamp (mA).
- Formula: I = Q/t halka:
- I= socodka korantada ee amps (A)
- Q= qarashka coulombs (C)
- t= waqti u dhexeeyo ilbiriqsiyo (s)
Liistada hoose waxay muujinaysaa dhufsanayaasha sida caadiga ah loo isticmaalo iyo kuwa hoose ee ampere:
- 1 MOm = 1,000 Ohm = 1 kOhm
- 1 mkOm = 1/1,000 Ohm = 0.001 Ohm = 1 mOm
- 1 nOhm = 1 / 1,000,000 0 XNUMX Ohm = XNUMX
Soo gaabinta
Qaar ka mid ah soo gaabinta caadiga ah waxay tixraacayaan hadda korontada ee aad la kulmi karto. Waxay kala yihiin:
- mA - milliamp (1/1000 amp)
- μA - microampere (1/1000000 ampere)
- nA – nanoampere (1/1000000000 ampere)
Sida loo isticmaalo ammeterka?
Ammeter-yadu waxay cabbiraan cadadka hadda ama socodka korantada ee amps. Ammeter-yada waxaa loogu talagalay in lagu xiro si taxane ah wareegga ay la socdaan. Ammeter-ku wuxuu bixiyaa akhrinta ugu saxsan marka wareeggu ku socdo culeys buuxa marka wax akhrinayo.
Ammeter-yada waxaa loo adeegsadaa codsiyada korantada iyo korantada ee kala duwan, inta badan waa qayb ka mid ah qalabka aadka u adag sida multimeters. Si loo go'aamiyo cabbirka ammeter-ka loo baahan yahay, waxaad u baahan tahay inaad ogaato inta ugu badan ee hadda la filayo. Markasta oo ay sareeyso tirada amps-ka, ayaa sii ballaaran oo dhumucda siliga looga baahan yahay isticmaalka ammeter-ka. Tani waa sababta oo ah hadda sare wuxuu abuuraa dhul birlab ah oo faragelin kara akhrinta fiilooyinka yaryar.
Multimeter-yadu waxay isku daraan dhowr hawlood oo hal qalab ah, oo ay ku jiraan voltmeters iyo ohmeters, iyo ammeters; Tani waxay ka dhigaysaa inay si cajiib ah faa'iido u leeyihiin codsiyo kala duwan. Waxaa caadi ahaan isticmaala koronto yaqaannada, injineerada elektarooniga ah iyo ganacsatada kale.
