Muchikamu che AC, kune marudzi maviri emagetsi emagetsi anopiwa kumutoro kubva pamagetsi emagetsi: imwe isimba rinoshanda uye imwe inobata simba.Kana mutoro wacho uri resistive load, simba rinoshandiswa isimba rinoshanda, kana mutoro uri capacitive kana inductive mutoro, kushandiswa isimba rinoshanda.Active power voltage uye yazvino muchikamu chimwe chete (AC simba ndiwo mutsauko pakati pesimba rinoshanda uye rinoshanda), kana voltage ichipfuura yazvino, inductive reactive simba;kana yazvino ichipfuura voltage, iri capacitive reactive simba.

Simba rinoshanda isimba remagetsi rinodiwa kuchengetedza kushanda kwakajairika kwemidziyo yemagetsi, ndiko kuti, kushandurwa kwesimba remagetsi kuita mamwe marudzi esimba (mechanical energy, light energy, heat) yesimba remagetsi.Semuenzaniso: 5.5 kilowatts yemagetsi emagetsi 5.5 kilowatts emagetsi emagetsi anoshandurwa kuita magetsi emagetsi, achityaira pombi kupomba mvura kana kupura nemuchina;midziyo yekuvhenekesa yakasiyana-siyana ichashandurwa kuva simba rechiedza, kuti vanhu vararame uye vashande chiedza.

Reactive simba rinowedzera abstract;isimba remagetsi rinoshandiswa pakuchinjana kwemagetsi nemagineti mukati medunhu uye kumisikidza nekuchengetedza simba remagineti mumidziyo yemagetsi.Iyo haishande kunze, asi inoshandurwa kuva mamwe marudzi esimba.Chero mudziyo wemagetsi une electromagnetic coil inoshandisa reactive simba kumisikidza magineti.Semuenzaniso, 40-watt fluorescent rambi inoda anopfuura 40 watts esimba rinoshanda (iyo ballast inodawo kushandisa chikamu chesimba rinoshanda) kuburitsa mwenje, asi inodawo anenge makumi masere ekuita simba rekuti ballast coil igadzirise inochinja magineti. munda.Nekuti haiite basa rekunze, kungonzi "reactive".
