RLC Circuit Analysis (Series And Parallel) In an RLC circuit, the most fundamental elements of a resistor, inductor, and capacitor are connected across a voltage supply. All of these elements are linear and passive in nature Figure 1 shows an RLC series circuit with an AC voltage source, the behavior of which is the subject of this section. The crux of the analysis of an RLC circuit is the frequency dependence of X L and X C, and the effect they have on the phase of voltage versus current (established in the preceding section). These give rise to the frequency dependence of the circuit, with important resonance features that are the basis of many applications, such as radio tuners 3 Section 8.1, 8.2 The Natural Response of a Parallel RLC Circuit 1.
