    Question

    When a capacitor is fully charged in a DC circuit, the

    current through it is:
    A Maximum Correct Answer Incorrect Answer
    B Constant Correct Answer Incorrect Answer
    C Zero Correct Answer Incorrect Answer
    D Infinite Correct Answer Incorrect Answer

    Solution

    In a DC circuit, once a capacitor is fully charged, no more current flows through it. The voltage across the capacitor equals the source voltage, and the capacitor behaves like an open circuit. Only during charging or discharging does current exist. Thus, after full charging, the current is zero.
