A series RLC circuit comprises a resistor (R), inductor (L), and capacitor (C) connected in a single path. The circuit's impedance depends on the frequency, with a characteristic resonance frequency where the inductive and capacitive reactances cancel each other. At resonance, the impedance is purely resistive, and the circuit can either attenuate or amplify signals. Series RLC circuits are crucial in applications like tuning, filtering, and signal processing in electrical and electronic system...

A parallel RLC circuit consists of a resistor (R), inductor (L), and capacitor (C) connected in parallel. It exhibits complex impedance behavior, combining resistive, inductive, and capacitive effects. The circuit's total impedance varies with frequency, leading to resonant behavior at a particular frequency where inductive and capacitive reactances cancel out. This makes parallel RLC circuits vital in tuning and filtering applications within communication and signal processing systems.
