Me yasa Tsarin Gwajin Resonant AC ke haifar da wuce gona da iri?

Mafi girman ƙarfin ƙarfin samfurin da aka gwada da kuma ɗigogi na reactance na na'urar gwajin gwaji, mafi ƙaranci tasirin ƙarfin ƙarfin.Don haka, lokacin da muke gudanar da gwajin ƙarfin ƙarfin AC na jerin resonance babban ƙarfin gwajin abu, ana buƙatar kai tsaye a auna ƙarfin lantarki a ƙarshen abin gwajin don hana abin gwajin fuskantar matsanancin ƙarfin lantarki.

Lamarin da ya wuce kima na na'urar gwajin resonance na jerin abubuwan yana faruwa ne ta abubuwa masu zuwa:

(1) Na farko ana matsawa ba zato ba tsammani a maimakon ƙarawa a hankali daga sifirin ƙarfin lantarki.
(2) Lokacin da akwai ƙarin ƙarfin lantarki, ba zato ba tsammani ka yanke wutar lantarki, maimakon a faɗi daidai gwargwado zuwa sifili sannan a yanke wutar lantarki.Ana iya gani daga tsarin canji na iska mai canzawa cewa yanayi biyu na sama zai haifar da wuce gona da iri akan samfurin da aka gwada, wanda ba a yarda da shi ba.
