I-Resistance R, inductance L, kunye ne-Capacitance C

I-Resistance R, i-inductance L, kunye ne-capacitance C zizinto ezintathu eziphambili kunye neeparitha kwisekethe, kwaye zonke iisekethe azikwazi ukwenza ngaphandle kwezi parameters ezintathu (ubuncinci enye yazo).Isizathu sokuba kutheni zizinto kunye neeparitha kukuba i-R, L, kunye ne-C ibonisa uhlobo lwecandelo, njengecandelo elichasayo, kwaye kwelinye icala, limele inani, njengexabiso lokumelana.

Kufuneka kucaciswe ngokukodwa apha ukuba kukho umahluko phakathi kwamacandelo esekethe kunye namalungu oqobo.Izinto ezibizwa ngokuba ziinxalenye kwisekethe ngokwenene ziyimodeli nje, enokuthi imele uphawu oluthile lwamacandelo okwenene.Ukubeka ngokulula, sisebenzisa isimboli ukumela uphawu oluthile lwezixhobo ezichanekileyo, ezifana nezichasi, iziko lombane, njl. Izibonda zokufudumeza zombane kunye namanye amacandelo anokumelwa kwiisekethe zisebenzisa amacandelo aphikisayo njengemizekelo yawo.

Kodwa ezinye izixhobo azinakumelwa licandelo elinye nje, njengokujijwa kwenjini, eyicoil.Ngokucacileyo, inokumelwa yi-inductance, kodwa i-winding nayo inexabiso lokumelana, ngoko ke ukuxhathisa kufuneka kusetyenziswe ukumela eli xabiso lokumelana.Ke ngoko, xa ulinganisa i-motor winding kwisekethe, kufuneka imelwe luluhlu lwendibaniselwano ye-inductance kunye nokumelana.

Ukuchasa yeyona nto ilula kwaye iqhelekileyo.Ngokomthetho ka-Ohm, ukumelana no-R = U/I, oku kuthetha ukuba ukuxhathisa kufana nombane ohlulwe ngoku.Ngokwembono yeeyunithi, ngu Ω=V/A, okuthetha ukuba ii-ohms zilingana neevolthi ezahlulwe ngee-ampere.Kwisekethe, ukuchasana kubonisa umphumo wokuthintela kwi-current.Okukhona ukuxhathisa okukhulu, kokukhona kunamandla isiphumo sothintelo kumbane wangoku… Ngokufutshane, ukuxhathisa akukho nto yakuthetha.Emva koko, siza kuthetha nge-inductance kunye ne-capacitance.

Ngapha koko, i-inductance iphinda imele amandla okugcina amandla ezinto ze-inductance, kuba ukuqina kwemagneti, kokukhona amandla enawo.Imimandla yemagnethi inamandla, kuba ngale ndlela, imagnethi inokusebenzisa amandla kwimagnethi kwindawo yemagnethi kwaye isebenze kuzo.

Yintoni ubudlelwane phakathi kwe-inductance, i-capacitance, kunye nokumelana?

I-Inductance, i-capacitance ngokwabo ayinanto yokwenza nokuchasana, iiyunithi zabo zihluke ngokupheleleyo, kodwa zihluke kwiisekethe ze-AC.

Kwii-resistors ze-DC, i-inductance ilingana nesiphaluka esifutshane, ngelixa i-capacitance ilingana nesiphaluka esivulekileyo (isiphaluka esivulekileyo).Kodwa kwiisekethe ze-AC, zombini i-inductance kunye ne-capacitance ivelisa amaxabiso ahlukeneyo okumelana nokutshintsha rhoqo.Ngeli xesha, ixabiso lokuchasana alisabizwa ngokuba yi-reactance, emele i-letter X. Ixabiso lokuchasana eliveliswa yi-inductance libizwa ngokuba yi-inductance XL, kwaye ixabiso lokumelana ne-capacitance libizwa ngokuba yi-capacitance XC.

I-inductive reactance kunye ne-capacitive reactance ifana ne-resistators, kwaye iiyunithi zazo zi-ohms.Ke ngoko, baphinda bamele isiphumo sokuthintela i-inductance kunye ne-capacitance okwangoku kwisekethe, kodwa ukuchasana akutshintshi ngokuphindaphindiweyo, ngelixa i-inductive reactance kunye ne-capacitive reactance change ngokuphindaphindiweyo.
