More Questions from RLC Circuits and Resonance

• What is the phase angle?
• What is the resonant frequency in the given circuit?
• The resonant frequency fo is 19 kHz.
• When inductive and capacitive reactance are present in the same series circuit, the magnitude of the total reactance is equal to the sum of the magnitudes of the individual reactances.
• The quality factor of a parallel circuit at resonance is VC/VS or VL/VS.
• The less selective a filter is, the steeper the slope of its curves at the cutoff frequencies.
• In a series RLC circuit, at above resonance the circuit is more capacitive than it is inductive.
• The bandwidth of a filter is the range of frequencies between the half-power frequencies.
• With the frequency given, the circuit in the given circuit is operating above resonance.
• If the output voltage were taken from across the resistor in the given circuit, the circuit would be a band-pass filter.
