    Q1. Why does a capacitor in a filter circuit smooth rectified AC?

    • A) Stores charge during peaks
    • B) Blocks DC component
    • C) Converts AC to DC
    • D) Reduces RMS voltage

    Answer: Stores charge during peaks

    Explanation: Capacitor discharges between AC peaks to maintain voltage. Option B describes a capacitor's inherent property unrelated to filtering.
