    Quality Factor (Q) in Series RLC Circuit

    • The quality factor (Q) in a series RLC circuit affects the bandwidth, where a high Q results in a narrow bandwidth and a low Q results in a wide bandwidth.
    • The ratio of resonant frequency to bandwidth in a series RLC circuit is equal to the quality factor (Q), i.e., Q = f₀ / Δf.
    • The quality factor (Q) relates to the ratio of energy stored to energy dissipated per cycle in a series RLC circuit.
    • The quality factor (Q) represents the selectivity or the sharpness of the resonance in a series RLC circuit, with higher Q indicating a sharper resonance.
