  1. Question 1

    Q1. A dielectric (κ=3) is placed between a 4 μF capacitor. What is the new capacitance if the capacitor remains connected to a battery?

    • A) 12 μF
    • B) 4 μF
    • C) 2/3 μF
    • D) 18 μF

    Answer: 12 μF

    Explanation: C = κC₀. Option B assumes voltage remains constant.
