RLC Series Circuit

RLC 串联电路

The RLC series circuit is a very important example of a resonant circuit. It has a minimum of impedance Z=R at the resonant frequency, and the phase angle is equal to zero at resonance.

RLC串联电路是共振电路的一个非常重要的例子。它在共振频率处具有最小的阻抗Z=R，且相位角在共振时等于零。

One way to visualize the behavior of the RLC series circuit is with the phasor diagram shown in the illustration above. The phasor diagram shown is at a frequency where the inductive reactance is greater than that of the capacitive reactance. This would occur at a frequency above the resonant frequency.

通过示意图可以形象地展示RLC串联电路的行为。示意图中显示的是在感抗大于容抗的频率下的情况。这种情况发生在共振频率之上。
