Indlela ekube- ngokulula milliamps ukuba amps, and vice versa

Lidla practice, kukho imfuneko ukuba kubalwe milliamps ukuba amps. Siye sazibonela zombane kunye nale ngxaki asivelanga. Kodwa iingcali makhwelo umntu yabucala enjalo ngoko nangoko ukuphendula. Njengenxalenye yale nqaku liza ukuchaza iindlela ezilula nezifikelelekayo ukwenza lo msebenzi.

inani ngokomzimba

Amperes - iyunithi ukuba kufunyaniswe inqaba yangoku. ixabiso yayo kugqitywa komlinganiselo ngqo kunye multimeter, ngumhloli okanye ammeter (indlela ethe ngqo). Le ngamandla ngoku lulinganiselwa kuphela uxhulumaniso series kwisekethe yombane kwesixhobo yokulinganisa. Kwimeko yesibini, ixabiso layo ingafunyanwa zokubala ngokwenza (indlela ngqo). Ukuba uyazi ukuba ombane isicelo kwinxenye umxokelelwane, ngokunjalo ukuqina kwayo, kwanele ukwahlula kuqala yesibini - kwaye ukufumana ixabiso olifunayo. Ekusebenzeni amps akunjalo wayedla - oku lixabiso elikhulu. Ngoko kuyimfuneko ukusebenzisa iiyunithi ezininzi - micro (10 ^-6) kunye milli (10 ^-3). Kodwa ubalo electrotechnical kufuneka ukuguqulela kulo unit main. (Umzekelo: milliamps ukuya amps). Khangela lo mzekelo ulandelayo. Le ombane kwi sekethe U = 6 V, kwaye ukuxhathisa R = 100 ohms. Ukumisela amandla I yangoku kuyo umthetho Ohm esithi:

I = U / R, (1)

apho:

• U - lo ombane kwi inxenye yesekethe V;
• R - ukuxhathisa le ohms isabelo;
• I - amandla A. DC kuso

Ngenxa yoko, izibalo sifumana I = U / R = 6/100 = 0,06 A. Akukho lula kakhulu ukuba inani okuqonda. Ngoko ke, oko iguqulelwa ibe ziiyunithi ezininzi. Kule meko iluncedo ukwazisa eli xabiso ku milliamperes. Ukulungiselela le njongo, ixabiso endibufumeneyo liphindaphindwe 0,06 A 1000 uze ufumane 60 Ma. Uyakwazi ukwenza uguqulo umva - milliamps ukuba amps. Ukuze wenze oku, bayahlule 60 Ma kwanele for 1000, kwaye ufumane zonke efanayo 0,06 A. Olu ukuguqulwa ubonwa milli ampere - 1000. Ngoko ke, sisahlula okanye phinda ngayo kule nombolo. Ukuba usebenzisa i isimaphambili "micro", kufuneka uye unit enye ukuya kwenye limele liphindaphindwe okanye lahlulwe kwesigidi.

inkqubo yokukala

Njengokuba bekutshiwo ngaphambili, sokulinganisa ammeters kul esetyenzisiweyo, multimeters kunye abahloli. Highest yemilinganiselo accuracy ezinikezelwa lokuqala kuzo. Baya umlinganiselo ixabiso enye kuphela kunye nobungakanani enye kuphela. Kwaye akukho elula kakhulu. Kwelinye icala, multimeters kunye abahloli ukwenzela ukuba umlinganiselo phantse onke amaxabiso zombane, hayi uluhlu kuphela mnye. Kwakhona, kwezi zixhobo bayakwazi ukuba ushintshele iiyunithi. Umzekelo, isixhobo ibonisa ukuba uluhlu kuyedlulwa. Kulo mzekelo, kufuneka batshintshele milliamps ukuba amps kwaye bafunde ixabiso. Eyona ethile omkhulu abahloli kunye multimeters kukuba, ngokungafaniyo ammeters, impazamo ke kakhulu ngakumbi. Kodwa, xa kusenziwa, ukuba adla ngokusetyenziswa, njengoko yenza kube lula ukufumana iingxaki ze alungise oko. Enye into ebalulekileyo enxulumene nezi zixhobo: ngaphambili ukuze uqiniseke ukuba ndimaphule umxokelelwane, abahloli ngoku wabonakala kunye multimeters, apho umlinganiselo amandla ngoku ngendlela licwecwe, okt ngaphandle uqhagamshelo. Loo isisombululo liya kusetyenziswa practice.

isishwankathelo

Guqulela milliamps ukuba amps Kukho iindlela ezimbini. Eyokuqala iqulathe ekuqhubeni izibalo lokubala eliguqukayo usebenzisa ezizodwa "1000" lomlingani (inani milli ampere). Indlela yesibini isekelwe phezu ukusetyenziswa izixhobo ezikhethekileyo yokulinganisa - tester kunye multimeter. Baye itshintshela ezizodwa akuvumela ukuguqula milliamps ukuba amps ngaphandle iingxaki kunye vice versa. Yeyiphi indlela elula kakhulu, kwaye ukusetyenziswa practice. Ukuba kukho ithuba lokuba bafunde ixabiso iseti ngokuthi yokubala, ngoko sebenzisa kanye ngale ndlela. Kungenjalo, uvavanyo lwenziwa, iziphumo, kwaye bazi inani elingaziwayo.
