Iyunithi yomlinganiselo yangoku - yintoni ntoni oko?

Ukususela ekuzalweni kwaye bonke ubomi engqongwe izixhobo zombane. Ezi ziquka: izixhobo zombane zasekhaya, bawabase amakhaya ethu kunye nezitalato, kuthetha unxibelelwano mobile, iimoto nanamhlanje namhlanje ihamba umbane. Zonke ezi zixhobo asele umbane, ezinye zivela-mbane makayithabathe, abanye idrayivu kwibhetri kunye nezihlanganisi, yaye ezinye eminye imithombo yamandla ( "kunye nephiko", iiphaneli zesola, njalo njalo). Kwaye abaninzi abantu bazi ukuba yintoni na iyunithi yokulinganisa ye amandla ngoku, yaye loo nto ngoku yombane? Kweli nqaku siza kuphendula le mibuzo.

Masiqalise kunye nezimaphambili ezingundoqo. Electrocution ebizwa zemiyalelo wayalela isindululo xa umqhubi amasuntswana icala. Cinga imiqathango ubukho yangoku:

• ubukho elektroni yamahala kumqhubi yesinyithi;
• kukho intsimi yombane (field eyenziwe ngenxa kumthombo yangoku).

Ngoku cinga into enjalo njengeyunithi womlinganiselo yangoku. Eli xabiso scalar luchazwa kunye ileta I. Determination Latin ratio intlawulo yangoku luyenziwa iiyunithi q, edlula kwicandelo umnqamlezo kumqhubi metal ukuya ubude bexesha t, ngexesha apho umsinga wombane ocande nombhexeshi. Ngako oko, ifomula imi ngolu hlobo lulandelayo: I = q / t. Iyunithi yomlinganiselo lwangoku lubonisa ntlawulo uya kucanda umnqamlezo candelo kwicingo kwiyunithi ngexesha ngalinye.

It intle elula. Ngoku cinga zeziphi iiyunithi eziqhelekileyo yangoku womlinganiselo. Akwanelanga ukuba bakhangele kwinkqubo ngamazwe leeyunithi (SI). Oku kulandela kule ukuba iyunithi langoku umlinganiselo - Ampere. Le yunithi yathiywa emva yamachiza French kwezezibalo André-Marie Ampere (1775-1836). Esi amagama afana electrodynamics, electrostatics, solenoids, EMF, galvanometer, electric current, ombane , kunye nabanye. Scientific AM Ampere ngenxa yokuqikelela kukuvela inzululwazi ezifana "cybernetics", iye yaba nguvulindlela intsebenziswano ngoomatshini kunye izinikezeli zombane ngoku zaziswa ulawulo lokuhlahla indlela ye yangoku.

Ngoku zama ukuqonda lo mbono ngokwembono physics sabaqalayo. Kuba oku kuyimfuneko ukuqaqambisa iimpawu sokuqukuqela yangoku yombane ngokusebenzisa ababhexeshi ezimbini ngaxeshanye. Ukuba amasuntswana ebizwayo lihamba kwi iingcingo ezimbini kwicala elinye, abaqhubi ezinjalo Kuza kutsalwa umdla, kwaye ukuba amasuntswana iza kuhamba kumacala ahlukeneyo, izinikezeli ziza badla ukubuyiselana. Iyunithi ye yangoku ampere umntu kuthathwa ukuba mandla apho iingcingo ezimbini engumzekelo wemitha enye ubude, ezahlulwe umgama oyimitha, uya banxibelelane 0,0000002N amandla.

Ukushwankathela, sithi ukuba ulwazi ingqiqo njengoko amandla yangoku efana, kuya kunceda ukuqinisekisa umlinganiselo wamandla asetyenziswa izixhobo zombane. Xa oku lula ukubala iintambo umthwalo ekhayeni lakho yaye, ke ngoko, ukukhusela amakhaya zabo emlilweni okanye umonakalo izixhobo zombane, nto leyo ke kaninzi kwenzeka xa unikezelo olungalunganga bendlu izixhobo zombane.
