hey guys, i was just wondering, in a series RLC circuit, is "R" the Thevinin's equivalent resistance at the "Capacitor and Inductor" terminals?, if not please correct me. Thanks.

tete9000 said:Hi berkeman, sorry if my question isn't well-clarified, what i meant is "When solving for V(t) or I(t) of an RLC circuit (series or parallel), the resistance in the circuit is taken to be the Thevenin's equivalent resistance at the terminals of both "the Capacitor and Inductor"?I'm not sure if this is right...so I'm asking you guys?is this right?if not please correct me.
berkeman said:Sorry that I'm not understanding the question. An ideal capacitor has infinite resistance, and an ideal inductor has zero resistance. Are you asking about the full complex impedance of the series combination of the R, L and C?
tete9000 said:exactly...i meant the series combination of a Resistor, Capacitor, and Inductor.

An RLC circuit is an electrical circuit that contains a resistor (R), inductor (L), and capacitor (C) connected in series. It is also known as a resonant circuit because it can exhibit resonance at a specific frequency.
In an RLC circuit, the resistor dissipates energy in the form of heat, the inductor stores energy in its magnetic field, and the capacitor stores energy in its electric field. When an alternating current (AC) is applied to the circuit, the inductor and capacitor will exchange energy back and forth, creating oscillations. The resistor will dampen these oscillations, resulting in a steady state response at the resonant frequency.
The resonant frequency of an RLC circuit is the frequency at which the inductive reactance and capacitive reactance cancel each other out, resulting in the highest current flow through the circuit. It can be calculated using the formula: f = 1/2π√(LC), where f is the resonant frequency, L is the inductance, and C is the capacitance.
The quality factor (Q) of an RLC circuit is a measure of the circuit's efficiency in storing and dissipating energy. It is calculated by dividing the reactance of the inductor or capacitor by the resistance of the circuit. A higher Q value indicates a more efficient circuit and a sharper resonant peak.
RLC circuits have many practical applications, such as in radio and television receivers, signal amplifiers, and filters. They are also used in power transmission systems, where they help improve power factor and reduce harmonics. Additionally, RLC circuits are used in electronic devices such as speakers, microphones, and electronic filters.
