The RLC Circuit Calculator computes key parameters of a resistor-inductor-capacitor circuit, including the time constant (τ = L / R), which indicates how quickly current changes in the RL portion; the resonant frequency (f₀ = 1 / (2π√(LC))), which is the frequency at which the circuit naturally oscillates; and the damping factor (ζ = R / (2√(L/C))), which determines whether the oscillations are underdamped, critically damped, or overdamped. This calculator is essential for analyzing RLC circuits in applications such as filters, oscillators, and transient response studies.
