Ilaha tamarta korontada, tilmaanta, noocyada iyo sifooyinka

Ilaha tamarta korontada ee meel kasta waxaa lagu kala duwanaayeen ay habka diyaarinta. Sidaas darteed, in bannaanka roona in ay isticmaalaan tamarta dabaysha ama badalo kulaylka ka dib gaaska sari shidaalka. In buuraha, oo meeshaas waxaa ku jira webi, dhisto biyo-xireenno iyo biyo kaxeeya ah marawaxadaha Rafaa. ciidanka Electromotive soo saaray meel ay sabab u tahay tamartaa kale ee dabiiciga ah.

Halkee ma macaamiisha awoodda

Ilaha tamarta korontada helay ka dib markii xoog danab diinta dabaysha, dhaqdhaqaaqa ogeed, socodka biyaha, natiijada dareen-nuclear, kulaylka ka gubashadii of gaaska, saliida ama dhuxusha. Quwadda baahsan, saldhigyada korontada. Tartiib tartiib yaraynta tirada dhirta nukliyeerka sida aan gebi ahaan ammaan ah oo dad ku dhow ku nool.

Waxaa loo adeegsan karaa falgal kiimikaad, kuwaas oo ifafaale dhawrno ee baytariyada baabuurta iyo qalabka guriga. Baytariyada ee telefoonada shaqeeyaan on mabda'a isku mid ah. Vetroviki loo isticmaalo meelaha la dabaysha joogto ah meesha ilaha awooda korontada ku jira design caadiga ah matoor awood sare.

In ay awoodda magaalada oo dhan mararka qaar ka mid ah saldhiga kuma filna, iyo ilaha awooda korontada lagu daro. Sidaas daraaddeed, on guryahooda Saanqaag Fidlo ah dalalka diiran rakibay cadceedda in ay ku quudiyaan qolalka shaqsi. Tartiib tartiib, deegaanka ilo saaxiibtinimo bedeli doona saldhiga, nijaasayn jawiga.

In baabuurta

gaadiidka Battery - ma aha meesha kaliya ee tamarta korontada. circuit baabuur loogu talagalay in hab in marka la guuro habka of diinta tamarta ogeed galay korontada bilaabmaa ah. Tan waxa u sabab matoor uu ku jiray wareeg ee gariiradda gudahood duurka ku magnetic abuuraa muuqaalka xoog ah electromotive (EMF).

Shabakadda bilaabo inuu qulquli hadda ku amraya batteriga, muddada hawlgalka of taas oo ku xiran ay capacitance. Xukun bilaamaa isla marka uu bilow engine ah. Taasi waa, tamarta la soo saaray by shidaalka gubanaya. horumar Recent ayaa loo ogol yahay gaari si ay u isticmaalaan ilaha EMF tamarta korontada si ay gaadiidka.

The baytariyada kiimikada koronto awood badan soo saaro hadda soo wareegi xidhan oo aad u adeegtaan sida il awoodeed. Halkan waxaa jira geedi socod dambe: EMF ah ee ku sugan gariiradda nidaamka drive ka dhigaya wareejin wheel ah. Hadda in miisaanka xawaaraha dardargelinta iyo gaariga circuit sare weyn saami.

Mabda'a hawlgalka ee gariiradda la magnet ah

Hadda dhex maraya gariiradda sababa ah talantaalli ah ka daadanayo magnetic. Waxa uu, ka bacdi, ayaa magnet sabaynta, taas oo ka dhigaysa jir ah oo leh labo polarities kala duwan daadgureyntaasi birlabta. Sidaas darteed, ilaha awooda korontada waa xarun loogu talagalay dhaqdhaqaaqa baabuurta.

Geedi socodka dambe, markay jir la magnet isku bedbedeli doono windings gudahood ay sabab u tahay tamarta ogeed u bedeli karaan talantaalli ah ka daadanayo magnetic in EMF gariiradda. Dheeraad ah, circuit ku dhajinta nidaamiyo danab in ay bixiyaan tilmaamayaasha sahayda loo baahan yahay. Sida ay mabda 'tani, waxay koronto ee dhirta korontada, Quwadda kaamerada.

EMF in Bannaanka u muuqataa in circuit xiran caadiga ah. Waxaa jira ilaa iyo inta kaari ka codsatay farqiga iman kara. waxaa loo baahan yahay ciidamo Electromotive si uu u sharaxo dabeecadaha ilaha tamarta. Qeexidda jirka waa: EMF wareegi xidhan yahay saamiyeed si ay shuqulka ciidamada dibadda, by dhaqdhaqaaqa lacag hal wanaagsan iyada oo jidhka oo dhan of kaari ah.

Formula: E = waxaan R - iska caabin ah waxaa loo arkaa dhamaystiran, marna laabi wax iska caabin ah gudaha ee il awoodeed iyo iska caabin ay ku daray qaybta loo nuujiyo Bannaanka.

Xadeyn ku saabsan rakibo of rugood,

kaari kasta by kaas oo ah socodka hadda abuuraa beerta koronto. il awoodeed waa gudbiye ah hirarka electromagnetic. Qiyaastii weyn rakiban, rugood, ama meel u dhow nooc matoor ee saameyn ku leh caafimaadka dadka. Sidaa darteed, talaabooyin in la xadido goobaha dhismaha ee u dhow dhismayaasha la deggan yahay ayaa loo qaaday.

Meel fog ka go'an in ay alaabta korontada, ka baxsan taas oo u shaqeeyo nool tahay mid nabdoon oo lagu rakibay heerka sharci-dejinta. Mamnuucay dhismaha xarumo-awood sare u dhow guryaha iyo waddada dadka. rakibaadda awood leh waa in la dhawro oo markaas dajisay galo.

Khadadka High-danab dhajinta sarreeya dhismayaasha iyo ka dhigaysa ka baxsan degsiimooyinka. Si aad u baabi'iyo saameynta ay hirarku electromagnetic in deegaan ka mid ah ilaha tamarta la xiray screens biraha earthed. In kiiska ugu fudud, mesh a of silig.

cutub oo cabbirka

il tamar kasta iyo circuit waxa lagu tilmaamay by baaxadda qiimaha taranta. Tani nayaa hawsha naqshadaynta iyo xisaabinta load hoos cunto gaar ah. Cutubyada waxaa isku xidhan by sharciyada jirka.

Waayo, qiyamka Koronto unugyada soo socda waxa loo xiraa:

• Resistance: R - Ohms.
• EMF: E - V.
• Reactance iyo impedance: X iyo Z - ohms.
• Hadda: I - amps.
• Danab: U - V.
• Power: P - watts.

Dhismaha wareeggeedii awood isku xigta iyo isku midka ah

circuit Xisaabinta waa adag, haddii xarunta isticmaalo ilaha tamarta korontada ee dhawr nooc. Xisaabta lagu darsadaa iska caabin ah gudaha ee laan kasta iyo jihada hadda marayo kirishbooyada ah. Waayo, mid kasta oo cabbirka isha EMF ah si gooni gooni ah looga baahan yahay iyo si degdeg ah u furi Bannaanka ee boosteejada of batteriga si loo cabbiro awood u qalab feed ah - voltmeter ah.

qalab circuit xiran tusi doonaa dhibic danab ka, taas oo uu leeyahay qiimo yar. inta badan u baahan yihiin ilaha kala duwan si ay u helaan awood ay lagama maarmaan tahay. Iyada oo ku xidhan codsiga isticmaali kartaa noocyada kala duwan ee isku xirnaanta:

• Joogto ah. EMF wareeggeedii il kasta ka kooban. Sidaas darteed, marka la isticmaalayo laba magacaaban baytariyada 2 volt helay by xira 4 V.
• Isku midka ah. Noocan ah isha waxaa loo isticmaalaa in la kordhiyo awoodda, siday u kala horreeyaan, waxaa jira waqti dheer ka hawlgala ka bateriga. EMF circuit marka la xidhiidha sida aysan waxba ka beddelin la siman baytariyada qiimaha magacaaban. Waxaa muhiim ah si ay u dhawraan polarity ee xiriir ah.
• xidhiidhada isku daro waxaa dhif ah loo isticmaalo, laakiin dhab ahaan waxaa. Xisaabinta emf ku sababtay soo saaray oo dhinac kasta u xiran yihiin. Waxaa la tixgelinayo polarity ee hadda iyo jihada laamaha.

Ohms dhaxe

iska caabin ah ayaa gudaha ee isha koronto waa la tixgeliyaa si loo go'aamiyo emf ku keeni doonaan. Guud ahaan, ciidanka electromotive xisaabiyaa by E caanaha = waxaan R + waxaan r. Halkee R - macaamiisha Resistance iyo r - iska caabin ah gudaha. dayrta ee danab la mid ah waxaa la xisaabaa ayadoo isla'egta soo socda: U = E - Ciir.

The hadda dal wareegi loo xisaabiyo sida uu qabo sharciga circuit buuxa Ohm, oo waan = E / (R + r). caabin Gudaha waa inay awoodaan inay saamayn ku xoog badan hadda. Si looga fogaado, il this xulay in ay load ah by qaanuunka soo socda: iska caabin ah isha gudaha waa in ay wax badan ka yar yahay wadarta iska caabin guud ee macaamiisha. Markaas tixgeliyaan qiimaha khasab ma aha in sababta oo ah goolasha ay yar oo baadi.

Sidee si loo cabbiro dhaxe Ohms?

Tan iyo ilaha iyo qaateyaasha ah ee tamarta korontada la isku raacay doonaa, ka dibna si degdeg ah su'aasha soo baxdo: sida loo qiyaaso iska caabin ah gudaha isha? Ka dib markii la Ohm-meter waxaa xiran oo aan xiriiro la awoodo laga heli karo iyaga. Si ay u xaliyaan dhibaatada la isticmaalayo oo gaabnaa ee hab aan toos ahayn - qiyamka looga baahan yahay doorsoomayaal dheeraad ah: hadda iyo danab. Xisaabinta waxaa la sameeyey sida ay r ah formula = U / I, halkaas oo U - dhibic danab ee guud ahaan iska caabin ah gudaha, iyo I - hadda soo wareegi jiray hoostiisa load.

Dhibic danab waxaa si toos ah lagu cabbiraa ee boosteejada il awoodeed. In Bannaanka yaqaan xiran yahay R. resistor ah Ka hor inta aan ka cabir magacaaban waa in la diiwaan by isha voltmeter ee EMF wareegi furan - E. dheeraad ah, load ku xiran yahay oo go'an akhrinta - U kululaynta. iyo I. hadda

Loo baahan yahay dhibic danab ee guud ahaan iska caabin U = E gudaha - kulaylka U. Sidaas darteed, soo r qiimaha count doonayo = (E - U RAR.) / I.
