In this paper,according to the condition of generating resonance in RLC series connection forced osillation,we analyze and discuss the RLC series connection route in detail,and conclude that only if the resonance that current is maximun in returned route is simple harmonic oscillation.
从RLC串联受迫振荡发生共振的条件出发 ,对其进行了分析与讨论 ,得出只有回路电流达最大值的共振是简谐振
