    Question

    Two capacitors of capacitance 6 ┬╡F and 3 ┬╡F are

    connected in series across a battery of constant voltage. The charges stored on the two capacitors in this setup are denoted as Q 1тАЛ and Q 2тАЛ, respectively. Now, both capacitors are disconnected and separately connected across the same battery (one at a time). Let the new charges stored on the 6 ┬╡F and 3 ┬╡F capacitors be Q 3тАЛ and Q 4тАЛ, respectively. Which of the following is the correct relation?
    A QтВГ > QтВД > QтВБ = QтВВ Correct Answer Incorrect Answer
    B QтВБ = QтВВ > QтВГ > QтВД Correct Answer Incorrect Answer
    C QтВГ > QтВБ = QтВВ > QтВД Correct Answer Incorrect Answer
    D QтВГ = QтВД > QтВБ = QтВВ Correct Answer Incorrect Answer

    Solution

    Case 1: Capacitors in Series When capacitors are connected in series, they have the same charge. Let the equivalent capacitance of the series combination be CS Assuming V is a positive value, we can establish the following inequality: 6V>3V>2V Therefore, Q3> Q4> Q1 = Q2
