Esiqeshini sokugcina, sikhulume ngobudlelwano phakathi kwe-Resistance R, inductance L, kanye ne-capacitance C , ngalokhu sizoxoxa ngolunye ulwazi mayelana nakho.
Ngokuqondene nokuthi kungani ama-inductors nama-capacitor ekhiqiza ukusabela kwe-inductive kanye ne-capacitive kumasekethe e-AC, ingqikithi ilele ekushintsheni kwamandla kagesi kanye namanje, okuholela ekushintsheni kwamandla.
Ku-inductor, lapho izinguquko zamanje, insimu yayo kazibuthe nayo iyashintsha (izinguquko zamandla).Sonke siyazi ukuthi ekufakweni kwe-electromagnetic, insimu yamagnetic eyenziwe ihlale ivimbela ukuguqulwa kwendawo yamagnetic yasekuqaleni, ngakho-ke njengoba imvamisa ikhula, umphumela walokhu kuvinjelwa uba sobala kakhulu, okuwukwanda kwe-inductance.
Lapho i-voltage ye-capacitor ishintsha, inani lenkokhelo epuleti le-electrode nalo liyashintsha ngokufanele.Ngokusobala, lapho i-voltage ishintsha ngokushesha, ukuhamba ngokushesha nangaphezulu kwenani lokushaja epuleti le-electrode.Ukunyakaza kwenani lenkokhelo empeleni kumanje.Kalula nje, lapho i-voltage ishintsha ngokushesha, iba nkulu yamanje egeleza ku-capacitor.Lokhu kusho ukuthi i-capacitor ngokwayo inomphumela omncane wokuvimba okwamanje, okusho ukuthi ukusabela kwe-capacitive kuyancipha.
Kafushane, i-inductance ye-inductor ilingana ngokuqondile nemvamisa, kuyilapho amandla e-capacitor ahambisana ngokuphambene nemvamisa.
Uyini umehluko phakathi kwamandla nokumelana kwama-inductors nama-capacitor?
Ama-resistors adla amandla kuwo womabili amasekhethi e-DC kanye ne-AC, futhi izinguquko ku-voltage nezamanje zihlala zivumelaniswa.Isibonelo, isibalo esilandelayo sibonisa i-voltage, amajika amanje, namandla aphikisanayo kumasekhethi e-AC.Kusukela kugrafu, kungabonakala ukuthi amandla okuphikisana nawo abelokhu ekhulu noma alingana no-zero, futhi angeke abe ngaphansi kuka-zero, okusho ukuthi i-resistor ibilokhu idonsa amandla kagesi.
Kumasekhethi e-AC, amandla asetshenziswa abaphikisi abizwa ngokuthi amandla amaphakathi noma amandla asebenzayo, achazwa ngohlamvu olukhulu P. Okubizwa ngokuthi amandla asebenzayo amelela kuphela izici zokusetshenziswa kwamandla kwengxenye.Uma ingxenye ethile inokusetshenziswa kwamandla, khona-ke ukusetshenziswa kwamandla kumelelwa amandla asebenzayo P ukukhombisa ubukhulu (noma isivinini) sokusetshenziswa kwayo kwamandla.
Futhi ama-capacitor nama-inductors awadli amandla, agcina kuphela futhi akhulule amandla.Phakathi kwazo, ama-inductors amunca amandla kagesi ngendlela yokuvusa amandla kazibuthe, athatha futhi aguqule amandla kagesi abe amandla kazibuthe, bese ekhulula amandla kazibuthe abe amandla kagesi, ephindaphinda ngokuqhubekayo;Ngokufanayo, ama-capacitor athatha amandla kagesi futhi awaguqule abe amandla kagesi, kuyilapho ekhulula amandla kagesi futhi ewaguqula abe amandla kagesi.
I-inductance kanye ne-capacitance, inqubo yokumunca nokukhulula amandla kagesi, ayidli amandla futhi ngokucacile ayikwazi ukumelwa amandla asebenzayo.Ngokusekelwe kulokhu, izazi zefiziksi zichaze igama elisha, okungamandla asebenzayo, amelwe izinhlamvu u-Q kanye no-Q.
