The current lags the voltage in the given circuit.
The voltage across the inductor is 77.8 volts.
This circuit is a high-pass filter.
The quality factor at resonance of a series circuit is VR/VL.
The impedance is 9684 Ω.
Series LC combinations are used more often in tuned amplifier circuits than are parallel LC combinations.
If the output voltage were taken across the resistor in the given circuit, the circuit would be a band-stop filter.
Resonance will occur when XC = XL in the circuit below.
The impedance is 160 Ω.
The greater the selectivity, the wider the bandwidth.
