    Question

    When two charged bodies are properly connected but do

    not exchange electric current, it indicates that they have the same _____.
    A Charge Correct Answer Incorrect Answer
    B Capacity Correct Answer Incorrect Answer
    C Resistivity Correct Answer Incorrect Answer
    D Potential Correct Answer Incorrect Answer

    Solution

    Electric current flows between two points only when there is a potential difference between them. According to Ohm’s law, current (I) through a conductor between two points is directly proportional to the potential difference (V) and inversely proportional to the resistance (R), (I = {V}/{R}). Hence, if two charged bodies have the same potential, no current will flow between them, regardless of their charge or capacity.
