Key Rules for Series Circuits: Current, Resistance, and Voltage

We can rearrange the same resistor, inductor, and capacitor from a series circuit into a parallel arrangement, yielding the following example. Impedance in Parallel Components Connecting the components in parallel does not alter their individual impedances. With the same supply frequency, the ind

Now that we’ve seen how series and parallel AC circuit analysis is not fundamentally different than DC circuit analysis, it should come as no surprise that series-parallel analysis would be the same as well, just using complex numbers instead of a scalar to represent voltage, current, and imp

When the inductive and capacitive reactances in a series LC circuit match, their impedances cancel, driving the total impedance toward zero. This phenomenon, known as series resonance, causes the circuit to behave like a short at the resonant frequency. Below is a schematic of a simple series resona

The principle that any periodic, non‑sinusoidal waveform can be decomposed into a set of sine waves of different frequencies is foundational in AC circuit analysis. When a circuit is driven by a waveform that is not a pure sine, the elements in the circuit respond as if a spectrum of frequency compo
