• X_L varies directly with frequency.X_L = 2pfL
• X_C varies inversely with frequency.

• Frequency has no affect on resistance.

A4. Decreases.
A5. Impedance lowCurrent high.
A6. Nonresonant (circuit is either above or below resonance).
A7. Inductor magnetic field.
A8. Capacitor.

A9. Natural frequency or resonant frequency (f _r).
A10. Maximum impedance, minimum current.
A11. At the resonant frequency.
A12.

A13. Bandwidth of the circuit.
A14. A filter.
A15. Low-pass. High-pass Bandpass. Band-reject.
A16. High-pass filter, low-frequency discriminator, or low-frequency attenuator.
A17. Low-pass filter, high-frequency discriminator or high-frequency attenuator.
A18. At low-frequency, a capacitor acts as an open and an inductor acts as a short.At high-frequency, a capacitor acts as a short and an inductor acts as an open.
A19. Frequency cutoff (f_co).
A20. Bandpass.
A21. Band-reject.
