Indlela kalula recalculate milliamps ukuba Amps, futhi okuphambene nalokho

Kaningi, practice, kukhona isidingo recalculate milliamps ukuze Amps. Sihlangabezena Electricians nale nkinga asivelanga. Kodwa ochwepheshe imfundamakhwela ka iphrofayela enjalo angase angasheshi usheshe uphendule ngazo. Njengengxenye akulesi sihloko achaza izindlela ezilula futhi ezingabizi ukwenza lo msebenzi.

ubuningi ngokomzimba

Amperes - iyunithi ukuthi quantifies ngamandla wamanje. Inani layo kungaba azimisele ngokusebenzisa nesilinganiso ngqo nge multimeter, umhloli noma ammeter (indlela eqondile). Amandla lwamanje kukalwa kuphela uxhumano uchungechunge yesifunda kagesi of instrument wokulinganisa. Esimeni sesibili, inani layo kungatholakala ngokufunda izibalo kokwenza (indlela engesobala). Uma wazi voltage isetshenziswa ingxenye yochungechunge, kanye ukumelana layo, kwanele ukuba uhlukanise ngowokuqala yesibili - futhi sithola ukubaluleka oyifunayo. Ngo umkhuba Amps akunjalo wayevame ukusebenzisa - lena ungowenani elikhulu. Ngakho-ke kuyadingeka ukusebenzisa amayunithi amaningi - micro (10 ^-6) kanye milli (10 ^-3). Kodwa izibalo electrotechnical kudingeka ukuhumusha wabayisa iyunithi main. (Isib milliamps ukuze Amps). Cabangela isibonelo esilandelayo. Voltage phezu wesifunda U = 6 V, kanye R ukumelana = ohms 100. Nquma osikweni mina lamanje kuso ngumthetho Ohm sika:

I = U / R, (1)

lapho:

• U - voltage ngesikhathi V wesifunda ingxenye;
• R - ukungawi ohms ingxenye;
• Mina - amandla A. DC kuso

Ngenxa yalokho, izibalo sithola mina = U / R = 6/100 = 0,06 A. Hhayi kakhulu esilungele inombolo okuqonda. Ngakho-ke, it is iguqulwe ibe amayunithi amaningi. Kulokhu kuba elula ukwethula lesi silinganiso e milliamperes. Ngenxa yale njongo, ukubaluleka etholwe iyanda yi 0,06 A 1000 ukuthola 60 ma. Ungenza ukuguqulwa reverse - milliamps ukuze Amps. Ukuze wenze lokhu, ukwehlukana 60 ma kumanele 1000, futhi uthole zonke okufanayo 0,06 A. Le ukuguqulwa ubonakala milli ampere - 1000. Ngakho-ke, thina uhlukanise noma kuphinde by le nombolo. Uma usebenzisa i- "micro" Isiqalo, une ukuya komunye iyunithi kwenye kufuneka iphindaphindwe noma ehlukaniswa esigidini.

inqubo ukulinganiswa

Njengoba kuphawuliwe ngaphambili, sokulinganisa amperage esetshenziswa ammeters, multimeters kanye abahloli. Aphakeme kakhulu nesilinganiso ukunemba olunikezwa wokuqala wabo. Bakala nenani elilodwa kuphela futhi ngezinga elilodwa kuphela. Futhi akusiyo elula kakhulu. Ngakwelinye ihlangothi, multimeters futhi abahloli ukukuvumela ukukala cishe wonke amanani kagesi, hhayi kuphela eyodwa ububanzi. Futhi, kulezi kumadivayisi unekhono ukuze ushintshe amayunithi. Ngokwesibonelo, insimbi ibonisa ukuthi ububanzi weqiwe. Kulokhu, kufanele ushintshele milliamps ukuze Amps futhi bafunde ukubaluleka. I ethile eyinhloko yabahloli futhi multimeters liwukuthi ngokungefani ammeters, iphutha angaphezu kakhulu. Kodwa namanje, ngokomthetho avame ukusetshenziswa, njengoba kwenza kube lula ukuthola inkinga kanye ukukulungisa. Eyokugcina ezibalulekile eziphathelene nalokho amadivayisi: ngaphambili ukuze siqiniseke ukuthi baphule iketanga, abahloli manje yavela futhi multimeters, okuyinto ukukala amandla zamanje ngendlela yokuxhumana, okungukuthi ngaphandle koxhumano. isixazululo enjalo uya iyasetshenziswa umkhuba.

isifinyezo

Humusha milliamps ukuze Amps Kunezindlela ezimbili. Eyokuqala siqukethe ekufezeni izibalo izibalo usebenzisa ekhethekile "1000" Coefficient (inombolo milli ampere). Eyesibili indlela kusekelwe ukusetshenziswa amathuluzi akhethekile wokulinganisa - ngumhloli futhi multimeter. Sinenkosi ukushintsha ekhethekile ezikuvumela ukuguqula milliamps ukuze Amps ngaphandle kwezinkinga, noHezekeli. Yikuphi indlela elula kakhudlwana, futhi ukusetshenziswa mkhuba. Uma kukhona ithuba ukuba zifunde ukubaluleka isethi by kuhlaziywa, bese usebenzisa ncamashi le ndlela. Kungenjalo, isivivinyo wenziwa, imiphumela zazo, futhi sazi ubukhulu engaziwa.
