RLC frequency limits Last week you studied the driven RC circuit and the driven RL circuit. Consider the driven series RLC circuit. Its impedance is Z=R+j(ωL−1/(ωC)) . (a) For very high frequencies the driven RLC circuit behaves like an RL circuit (the effect of the capacitor becomes negligible). In this case does the current lead or lag the applied voltage in phase? A. lags B. leads C. neither What value in degrees does |ϕ| approach as ω→∞ ? (b) For...
How does the current in an RC circuit depend on frequency? Explain the physics behind this dependence.
The cutoff frequency for RC filters (both low-pass and high-pass) is fe-1/2TRCHz. The cutoff frequency for RL filters (both low-pass and high-pass) is fe-R/2TL Hz. To convert gain H to gain in dB: hrdB) = 20 log 10 H. (Note: Gain is generally unitless, because H-Vout/ yn which has units volts,vots.
