  1. Question 1

    Q1. Why does the quality factor (Q) of a resonant circuit affect its selectivity?

    • A) Higher Q means narrower bandwidth
    • B) Lower Q increases component lifespan
    • C) Q controls voltage amplification
    • D) Higher Q reduces power consumption

    Answer: Higher Q means narrower bandwidth

    Explanation: Q determines frequency selectivity range. Option C is a secondary effect of resonance, not selectivity.
