A gaba siga cewa an dauki la'akari lokacin kirga na yanzu ikon ƙarfin lantarki ne. Ganin cewa lantarki - shi ne ma'ana motsi na barbashi da ciwon cajin don ƙirƙirar motsi zama dole a yi da lantarki filin. Saboda haka, irin ƙarfin lantarki ganewa darajar da aka lasafta rabo na yanzu aiki a kan wani takamaiman ɓangare na sarkar ga cajin sunã gudãna shi. A naúrar na ƙarfin lantarki, aka yanke shawarar zuwa Take volts (V), wanda shi ne rabo na jiki naúrar na aikin da naúrar cajin J. CL.

Yin amfani da wani ammeter haɗa da kewaye a jerin, sanin girma da yanzu ƙarfi, kuma a voltmeter alaka a layi daya - ƙarfin lantarki. Ikon halin yanzu an riga an ƙaddara analytically ta halitta sakamako a kan irin ƙarfin lantarki. La'akari da a baya na samu jiki siga kayyade samu ikon naúrar J / s ko daya Watt (W). A aikace, mun dauke da wani misali na lissafi a cikin wani manufa hali a cikin abin da Ya ƙaddara DC iko.

Wannan kawai sau da yawa a yau da kullum yi muna anfani da uku-lokaci na yanzu. Mun sanin ikon na uku-lokaci na yanzu a matsayin Naira Miliyan Xari da karfin kowane mutum lokaci. Ganin cewa kowane daga cikinsu aiki a AC yanayin, da ikon factor lissafi da aka kara wa aza ikon factor cos j.

Idan akai la'akari da jimlar halin yanzu damar domin hanyoyi daban-daban na a haɗa wani kaya ne na uku-lokaci na yanzu (da muka sani akwai biyu - alwatika kuma star), za mu ga cewa bayan wani sauki ilmin lissafi canji dabara domin lissafi a lokuta biyu ya dauki wannan ra'ayi.
