Reactance The yeelista in circuit AC ah

Resistance in wareegga korantada waa laba nooc - firfircoon oo Waxyeelo. resistors Active wakiil, incandescent, gariiradda kululaynta iyo wixii la mid ah. In si kale loo dhigo, dhamaan qaybaha ay ka dhex socodka hadda si toos ah u qabata shaqo waxtar leh ama, haddii ay dhacdo gaar ah, si loo soo saaro kaari ah kululaynta doonayo. Taa baddalkeeda, jet ah - dheer dalad. Waxaa loola jeedaa in reactance ah capacitive iyo yeelista. xubno circuit The isagoo reactance ah, marinka ee hadda korontada dhici diinta kala duwan tamarta dhexe. capacitor A (capacitance) ururayaa amarka, ka dibna u soo diro si loop ka. Tusaale kale - reactance u yeelista of gariiradda, Gudaheedana waxaa qayb ka mid ah tamarta korontada waxaa beddelay beer magnetic.

Dhab ahaantii, "daahir ah" ama ma reactances firfircoon. Had iyo jeer qayb ka soo horjeeda joogo. Tusaale ahaan, marka la xisaabinayo fiilooyin ee khadadka korontada long-distance, tixgeliyaan oo keliya ma iska caabin ah, laakiin sidoo kale capacitive. Iyo tixgelinta reactance u yeelista, waa in la xusuusnaado in labada kirishbooyada iyo korontada waxaa samaynta qaar ka mid ah isbedel ku xisaabinta.

By go'aaminta iska caabin guud ee qayb Bannaanka, waxaa lagama maarmaan ah in la isku laab ka kooban firfircoon oo Waxyeelo. Waxaa intaa dheer, si aad u hesho lacag toos ah oo ka mid ah hawlaha xisaabta caadiga ah wax aan macquul aheyn, sidaas isticmaali (dulinka) joomateri hab si ay u dhisaan. Dhistaa xagalka toosan kuwaas oo cathetus laba yihiin impedance firfircoon iyo yeelista, iyo shakaal - buuxda. Dhererka qaybaha ay u dhiganta qiimaha hadda.

Tixgeli reactance yeelista in circuit AC ah. U taaga circuit fudud oo ka kooban il awoodeed oo ah (emf, E), resistor ah (qayb resistive, R) iyo gariiradda (inductance, L). Tan iyo reactance u yeelista waxaa sabab u ah EMF is-laaluusheen (E B) ee markooda ee gariiradda, waxaa iska cad in u kordhiyaa la inductance circuit iyo qiimaha kordhay ee hadda ku dhex maraya Bannaanka.

sharciga Ohm ee circuit this u eg:

E + E B = waxaan R.

Ka dib markii la go'aaminayo derivative waqtiga hadda ah (I habaeynba) si ay u xisaabiso is-induction:

si E = -L * waxaan aaro.

"-" calaamad in isla'egta waxay muujinaysaa in saamaynta E si toos ah ka gees ah la beddelo qiimaha hadda. Lenz sharci dhigayaa in haddii ay jiraan wax isbeddel ah in EMF is-laaluusheen hadda. Tan iyo markii isbedel sida in wareeggeedii AC waa dabiiciga ah (oo ay si joogta ah), E B foomamka iska caabin ah la taaban karo ama iska caabin ah ayaa sidoo kale run. In case of il awoodeed oo ka mid ah hadda si toos ah , xiriirka this ma ku qanacsan tahay iyo marka isku day ah in ay ku xidhmaan gariiradda (inductance) wareegi noocan oo kale ah uu doonaynin-circuit gaaban dhacay classic

In ay ka gudbaan B sahayda E awood u waa in ay curiyaan kala duwan ka iman karta natiijooyinka coil in ay ahayd filan, ugu yaraan on magdhow iska caabin ah si E ah. Waxaa soo socota:

U = si cat -E.

In si kale loo dhigo, danab oo dhan inductor waa tiro ahaan siman yihiin in ay ciidanka electromotive is-induction.

Tan iyo markii la sii kordhaya ee hadda ka jirta Bannaanka kordhiyaa duurka ku magnetic markeeda abuuraa beerta Eddy keenaya koritaanka in inductance countercurrent, mid ka mid ah u sheegi kartaa in uu jiro wareeg wajiga u dhexeeya danab iyo hadda a. Sidaa mid feature, maxaa yeelay, is-induction EMF ka hortagtaa wixii isbeddel ah ee hadda, marka u kordhiyaa (muddada quarter ugu horeysay ee sinusoid ah) counter beerta ahbaa, laakiin dayrta (muddada labaad) on lid ku ah - hadda laaluusheen waa codirectional la saldhigga. Taasi waa, haddii postulate ah jiritaanka il awood fiican iyagoon wax iska caabin gudaha iyo inductance aan qayb firfircoon, tamarta gariirka "il - gariiradda" dhici kara muddo aan la cayimin.
