Yintoni na le ngoku sinusoidal

Into yokuba ifildi yokuKhangela sinusoidal tihamba izinikezeli ingcingo indlu, weva yonke into. Kodwa ke ukuba umntu ezingaqhelekanga kunye zobunjineli yombane, imiqathango "sine" yaye, ingakumbi, "bume", kuthiwa nto. Kweli phepha, sizama ukunika uluvo jikelele kuyo, kulula ukuqonda ukuba wonke.

Okokuqala, kufuneka ukumisela umyalelo loo yangoku yombane. Ngokutsho iinkcazo langoku yangoku - ngqo ukuhamba amasuntswana nezakhiwo ukuba isigxina uphawu oluvumelanayo okanye embi. Ngokuqhelekileyo, amasuntswana ze-elektroni ukuqonda, kodwa oku akuyonyani. Atom elahlekelwe electron ngenxa protons abakhoyo nucleus izuza isimangalo entle, abe ion. EMF kuchaphazela kuphela electron kodwa kuyo. Kwanele ukuba ukukhumbula ukuba, ebalelwe kwicala ezintle intshukumo yangoku evela plus ku thabatha, nangona eneneni, amasuntswana embi ityala sihambe ngendlela eyahlukileyo.

Ziphi ezi amasuntswana? Bonisa isakhiwo umqhubi: akhazimlayo efestileni kunye atom kwiindawo. ingaphezulu ngalunye kalukhuni ichazwa njenge inkqubo elincinane elanga. Embindini i core omkhulu eliquka protons kunye neutron, kwaye electron ukuhamba kwindawo yazo ngeenxa zonke.

Nesigxina Proton yi electron ezilungileyo nezingalunganga, ngoko ke ngokufanayo nomtsalane. Ukusondela ngumongo, ngokuqina intsebenziswano. Current kwavela imfuneko atom simahla electron yaye kubangele ukuba sihambe ngendlela efunekayo. Abavelisi lo msebenzi olwenziwe ngempumelelo phandle i batshintshana zibuthe. Kuthiwa electron amandla elishiyiweyo kwesi zisuke zangaphezulu, isisi sawo. Kakade ke, akukho traffic ngqo. Lo utshintshiselwano ezi amasuntswana phakathi atom elikufutshane.

Phi igama "lwangoku sinusoidal"? Isizathu sokuba le ndlela imveliso. Simela nezibonda ezimbini ahlukeneyo umazibuthe, naphakathi kwemigca amandla entsimini. Thina beka kukwisakhelo umqhubi kweli candelo. injongo yawo uqhagamshele zibotshiwe, kusekwe ndzhendzheleko (circuit). Batshintshana bezel. Okwangoku xa ibekwe enxuseneyo iindawo zale umazibuthe, akukho yangoku kuba akukho kwisiphambuka se- imigca kwempixano (omabini amacala yesakhelo zizinto ithoyilethi). Apha luvuliwe kancinane, imigca lo mhlaba otsalayo kuwela umqhubi, ukukhululwa electron kwaye ngoku kuvela.

Ngelo xesha elinye kwelinye icala isakhelo kwaye icanda endle, kodwa kwelinye icala. Elona xabiso liphezulu zangoku - kunye nokubekwa nkqo. Sinusoidal yangoku - lumelo olubonakalayo yale nkqubo. Ngaphandle kube nzima ukuqonda ukusebenza izixhobo zombane. Igrafu ebonisa current sinusoidal imela cartesian ekulungelelaniseni kule nqwelo-moya. Le iasi eme nkqo ngoku ilibele, kwaye nkqo - ixesha. Ngenxa ngexesha isakhelo ukujikeleza amaxabiso ngxelo ngamaxesha ngokuphindaphindiweyo, yenziwa ezahlukeneyo ngoku sinusoidal kwicala kunye nokubaluleka. Kwenziwa ufana nokulatyuza sine kwi ixesha axis, ukususela kwinxalenye ibekwe ngaphezu esqwini lwamaza (a uphawu oluvumelanayo), yaye inxalenye ephantsi (negative). Ingongoma eliphezulu ngamaza bahambelana kwisakhelo kwindawo engqamene nomgca imigca ngobunzulu asendle, kwaye kuhlangana ixesha axis (current zero) - nkqo.

yombane sinusoidal yangoku kakhulu ngokubanzi, njengoko olu hlobo lwamandla kakhulu nje waguquka ngenxa abaguquli kunye nezinye izinto yombane, nokuvumela ukudluliselwa imigama ezinkulu, kunye kwezwi efunekayo. Ngaphandle, umgaqo isizukulwana lubandakanya ukudaleka current sinusoidal.
