在并联交流电路(图一)中,阻抗随电路参数(如L,C等)或电源频率ω的变化情况,以及谐振现象等问题,一般电磁学或电工等书中都讨论得不多,而某些书中的阐述也还存在不够严密之处。因此,本文拟就并联谐振电路的特性,作进一步的探讨。 In the parallel AC circuit (Figure 1), the impedance with the circuit parameters (such as L, C, etc.) or the power frequency ω changes, and the phenomenon of resonance and other issues, the general electromagnetics or electrician are discussed in the book is not much, and Some of the book’s exposition is still not tight enough. Therefore, this paper intends to parallel resonant circuit characteristics for further discussion.
