  1. Question 1

    Q1. In an RLC circuit, increasing resistance affects the resonance curve. What change is observed?

    • A) The curve becomes narrower and taller.
    • B) Resonance frequency increases.
    • C) The curve becomes broader and shorter.
    • D) Impedance becomes purely inductive.

    Answer: The curve becomes broader and shorter.

    Explanation: Higher resistance increases damping, broadening the curve. A is incorrect because damping reduces peak height.
