Kwisicatshulwa sokugqibela, sithethe ngobudlelwane phakathi kwe-Resistance R, inductance L, kunye ne-capacitance C, ngale ndlela siza kuxoxa ngolunye ulwazi malunga nabo.
Ngokuphathelele kutheni i-inductors kunye ne-capacitors zivelisa i-inductive kunye ne-capacitive reactances kwiisekethe ze-AC, i-essence ilele kwiinguqu ze-voltage kunye nezangoku, ezikhokelela kutshintsho kumandla.
Kwi-inductor, xa utshintsho lwangoku, intsimi yayo yamagnetic iyatshintsha (utshintsho lwamandla).Sonke siyazi ukuba kwi-electromagnetic induction, i-magnetic field induced isoloko ithintela utshintsho kwintsimi yamagnetic yasekuqaleni, ngoko ke njengoko i-frequency inyuka, umphumo walo mqobo ubonakala ngokucacileyo, oko kukuthi ukwanda kwe-inductance.
Xa i-voltage ye-capacitor itshintsha, inani lentlawulo kwi-electrode plate nayo iyatshintsha ngokufanelekileyo.Ngokucacileyo, ukukhawuleza kwe-voltage utshintsho, ngokukhawuleza nangaphezulu ukuhamba kwexabiso lentlawulo kwipleyiti ye-electrode.Ukuhamba kwexabiso lentlawulo ngokwenene okwangoku.Ukubeka ngokulula, ukukhawuleza kokutshintsha kombane, kokukhona umbane uqukuqela ngecapacitor.Oku kuthetha ukuba i-capacitor ngokwayo inefuthe elincinci lokuthintela okwangoku, oku kuthetha ukuba i-capacitive reactance iyancipha.
Isishwankathelo, i-inductance ye-inductor ihambelana ngokuthe ngqo kwi-frequency, ngelixa i-capacitance ye-capacitor ihambelana ngokungafaniyo ne-frequency.
Yintoni umahluko phakathi kwamandla kunye nokuchasana kwee-inductors kunye ne-capacitors?
I-Resistors isebenzisa amandla kuzo zombini iisekethe ze-DC kunye ne-AC, kwaye utshintsho kwi-voltage kunye neyangoku zihlala zilungelelaniswa.Umzekelo, lo mzobo ulandelayo ubonisa i-voltage, yangoku, kunye ne-curves yamandla ye-resistors kwiisekethe ze-AC.Ukusuka kwigrafu, kunokubonwa ukuba amandla e-resistor ahlala ekhulu okanye elingana no-zero, kwaye akayi kuba ngaphantsi kwe-zero, oku kuthetha ukuba i-resistor iye yathatha amandla ombane.
Kwiisekethe ze-AC, amandla asetyenziswa ngabaxhamli abizwa ngokuba yi-avareji yamandla okanye amandla asebenzayo, achazwa ngunobumba omkhulu P. Okubizwa ngokuba amandla asebenzayo abonisa kuphela iimpawu zokusetyenziswa kwamandla kwecandelo.Ukuba icandelo elithile linokusetyenziswa kwamandla, ngoko ukusetyenziswa kwamandla kubonakaliswa ngamandla asebenzayo P ukubonisa ubukhulu (okanye isantya) sokusetyenziswa kwamandla.
Kwaye i-capacitors kunye ne-inductors ayidli amandla, igcina kuphela kwaye ikhulule amandla.Phakathi kwazo, ii-inductors zithatha amandla ombane ngendlela yokuvuselela amandla ombane, athatha kwaye aguqule amandla ombane abe yimagnethi yamandla, aze akhulule amandla ombane kumandla ombane, ngokuphindaphindiweyo;Ngokufanayo, ii-capacitors zithatha amandla ombane kwaye ziguqule zibe ngamandla ombane, ngelixa zikhulula amandla ombane kwaye ziguqulelwe kumandla ombane.
I-Inductance kunye ne-capacitance, inkqubo yokuthatha kunye nokukhulula amandla ombane, musa ukusebenzisa amandla kwaye ngokucacileyo ayikwazi ukumelwa ngamandla asebenzayo.Ngokusekelwe kule nto, i-physicists ichaze igama elitsha, elinamandla asebenzayo, amelwe ngoonobumba u-Q kunye no-Q.
