Electronics Handbook/Circuits/RLC Series

RLC Series right|200px Circuit Analysis Circuit's Impedance Natural Response ± . There is only one real root, s = -αt = , There are two real roots, ± = , There are two complex roots, ± = Current change with time depends on the value of R L and C . Dòng điện giảm dần theo hàm số mủ của e . Dòng điện giảm đến một giá trị âm rồi tăng đến một giá trị dương . Mạch điện có có Dòng Điện của Sóng Sin giảm dần theo theo thời gian Resonance Response At resonance . Analyze the circuit at . Capacitor opens circuit . Inductor opens circuit . At resonance, series RLC is capable of select a bandwidth of frequencies where voltage is stable does not change with frequencies. Therefore, can be used as Tuned - Resonance Band Pas Selected Filter Summary The natural Response of the RLC series is a second order differential equation of current Depends on the value of Resistance the equation has {| class="wikitable" width=100% ! One Real Root !! Two Real Roots !! Two Complex Roots |- | One real root || Two real roots || |} At Resonance when all the frequency dependent components cancel out RLC series behaves like Tuned Resonance Selected Band Pass Filter
