When exploring the values for real circuits, it is easy to find examples where both VL and VC are larger than the resultant voltage V. This can occur because these voltages VL and VC act 180° out of phase with each other. You can visualize this from the phasor diagram by seeing that both VL and VC can be large and that they exactly cancel each other at resonance.

在研究实际电路的值时,很容易遇到这样的例子:V_L和V_C都大于结果电压V。这可能发生是因为这些电压V_L和V_C彼此相位相差180°。你可以从相量图中直观地看到,V_L和V_C都可以很大,并且在共振时恰好相互抵消。
