Electronics-RLC Circuits and Resonance
11. If the bandwidth of a filter increases:
- Q decreases
- the roll-off rate increases
- the half-power frequency decreases
- the center frequency decreases
12. Which statement best describes reactance in a series RLC circuit?
- Capacitive reactance is always dominant.
- Inductive reactance is always dominant.
- Resistance is always dominant.
- The larger of the two reactances is dominant.
13. Voltage lags current in an RLC circuit when it acts:
- capacitively
- resistively
- inductively
- resonantly
