The less selective a filter is, the steeper the slope of its curves at the cutoff frequencies.

More Questions from RLC Circuits and Resonance

• 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.
• The impedance is 1177 Ω.
• The current through the inductor is 5 amps.
• If the given circuit were at resonance, the total current would be at its maximum.
• If the given circuit in were operating at resonance, the total current would be maximum.
• By increasing the resistance of a coil you can increase the Q of the coil at resonance.
