33. Which statement is true?

A. A series resonant circuit is of high impedance

B. A parallel resonant circuit is of low impedance

C. A series resonant circuit is inductive if it operates at a frequency higher than the resonant frequency

D. A parallel resonant circuit is inductive if it operates at a frequency higher than the resonant frequency

Consider the following voltage divider circuit: 

Identify the circuit as either a high pass filter, low pass filter, band pass filter, band stop filter or none of the above. 

The circuit above, is known to exhibit a resonance at a frequency given by ω02=1/LC. Show that the 3dB bandwidth of the circuit around this resonance is given by δω3dB=R/L. 

The following three impedances are connected in series across a 40 V, 20 kHz supply: a 
resistance of 8 Ω, a coil of inductance 130 μH and 5 Ω resistance, and a 10 Ω resistor in 
series with a 0.25 µF capacitor. Sketch a neat diagram representing this network, and 
calculate:
5.1.1 The inductive and capacitive reactance’s. (4)
5.1.2 The magnitude and phase angle of the circuit impedance. (4)
5.1.3 The voltage drops across resistance, inductance and capacitance.

5. The following circuit can be used as part of a loudspeaker crossover network. These networks can be pictured as frequency sensitive voltage dividers. This circuit allows low frequency tones to go into the low frequency transducer labeled here as "Loudspeaker", a.k.a. woofer. The crossover frequency is the frequency f at which the reactance magnitude equals the woofer's resistance.
