MDCAT Physics MCQ #1535

  1. Question 1

    Q1. The capacitance of a parallel plate capacitor is 5 pF. If the area of the plates is doubled, the new capacitance is

    • A) 10 pF
    • B) 20 pF
    • C) 5 pF
    • D) 2.5 pF

    Answer: 10 pF

    Explanation: C ∝ A, so doubling A doubles C to 10 pF. Wrong options misunderstand effect of area on capacitance.
