Theoretical Overview

RC Circuit (Resistor-Capacitor)

An RC circuit consists of a resistor (R) and a capacitor (C) connected in series or parallel. It is widely used for signal filtering, timing applications, and transient analysis. The time constant τ = R×C determines the charging and discharging speed of the capacitor.

RL Circuit

An RL circuit is composed of a resistor (R) and an inductor (L). It is commonly used for transient response and filtering in AC circuits. The time constant τ = L/R determines the current growth/decay speed.

RLC Circuit

An RLC circuit includes a resistor (R), an inductor (L), and a capacitor (C). It exhibits resonance behavior at frequency f₀ = 1 / (2π√LC) and is widely used in oscillators, filters, and tuning circuits.
