Chinhu chesimba chinoratidzira kugona kweRed headlampkubuda simba rinoshanda. Simba chiyero chekutapurirana kwesimba, uye muDc zvisizvo zveChokwadi v uye zviripo zvechiripo, izvo zvinowanzoitika. Musiyano uripo pakati pekuponesa simba uye simba chairo rinotungamira kuchinhu chesimba, uye chinhu chesimba chakaenzana nehuremu hwesimba chairo rekuita simba. Saka simba chairo riri muAC system yakaenzana kune inovimbika simba nguva iyo simba.

Simba Rinoshanda: Chigadzirwa che AC Voltage uye AC ikozvino. Nefomula se: s = ui. Kupi s kwakarambidzwa kubuda simba mu VA (Volt-ampere); Iwe wakarambidzwa kubudiswa voltage mu v, senge 220v, 380v, nezvimwewo.; Ini ndakabvumidzwa kubuda kunze kwechizvino muA. Simba rinooneka rine zvikamu zviviri: Simba rinoshanda (p) uye simba rekushanda (Q). Simba rinoshanda rinoreva chikamu chebasa rakaitwa zvakananga. Semuenzaniso, mwenje kumusoro, kutenderera kwemotokari, kutenderera kwedunhu remagetsi rinoshanda. Nekuti simba iri rave kupisa, rinogona kunzwiwa zvakananga nevanhu, saka vamwe vanhu vane kunyepedzera, ndiko kuti, iro simba rinoshanda sesimba rinooneka, rinoziva simba rinoshanda rinongova chikamu che
Simba rinooneka, neFomula: P = SCOS θ = Uicosθ = UIF. Iko P is is active simba mu w (watts); F = cos θ inonzi iyo Simba Facector, uye ž iri musiyano wekusiyana kwemapepa akasiyana emapepa emapepa asiriyeya. Simba rehunyanzvi ndiyo chikamu chesimba rakachengetwa mudunhu racho asi risingashandiswe zvakananga, rinoratidzwa neforamu: Q = SSIN θ = Uisinin. Uko q is active simba muVar (kushaya).
