RLC电路

串联RLC电路：电阻、电感和电容
动画演示了LC电路（无电阻的RLC电路）的工作。电荷在电容器极板和电感之间来回传递。能量在电容器的电场 (E) 和电感的磁场 (B) 之间来回振荡。 RLC电路工作情况类似，不同之处在于，由于电路中的电阻，随着时间变化振荡电流衰减至零。
图 1. RLC串联电路 V - 电源电压 I - 电路电流 R - 电阻 L - 电感 C - 电容

RLC电路是一种由电阻（R）、电感（L）、电容（C）组成的电路结构。LC电路是其简单的例子。RLC电路也被称为二阶电路，电路中的电压或者电流是一个二阶微分方程的解，而其系数是由电路结构决定。

若电路组件都视为线性组件时，一个RLC电路可以被视作电子谐波振荡器。

这种电路的固有频率一般表示为：（单位：赫兹Hz）

f_c = {1 \over 2 \pi \sqrt{L C}}

RLC电路常用来作带通滤波器或带阻滤波器，其Q因子可以由下式得到：

Q = {f_c \over B_W} = {2 \pi f_c L \over R} = {1 \over \sqrt{R^2 C / L}}

RLC电路的组成结构一般有两种：分别是串联型及并联型。

RLC circuit RLC电路

A series RLC circuit: a resistor, inductor, and a capacitor
Animation illustrating the operation of an LC circuit, an RLC circuit with no resistance. Charge flows back and forth between the capacitor plates through the inductance. The energy oscillates back and forth between the capacitor's electric field (E) and the inductor's magnetic field (B) RLC circuits operate similarly, except that the oscillating currents decay with time to zero due to the resistance in the circuit.
Figure 1: RLC series circuit V, the voltage source powering the circuitI, the current admitted through the circuitR, the effective resistance of the combined load, source, and componentsL, the inductance of the inductor componentC, the capacitance of the capacitor component

An RLC circuit is an electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C), connected in series or in parallel. The name of the circuit is derived from the letters that are used to denote the constituent components of this circuit, where the sequence of the components may vary from RLC.
