摘要
通过对并联电容器容值计算公式C=PwU2(tanΦ1-tanΦ2)的两种推导方法的讨论,证明了在交流电路中,交流量的不同表示方法之间是等效的,而在求解相关问题时,选用不同的表示方法,会对求解问题的复杂程度产生比较明显的影响。
Through the comparison of the two derivations of the formula for the capacity of the capacitor, this paper proves that in AC circuit the different expressions of AC quantity are equivalent, but their applications obviously influence the difficulty of the problem solution in some conditions.
