    Question

    A wire is bent into a circular loop. If current is

    passed through it, which one of the following statements is valid?
    A Electric field inside the wire is zero everywhere Correct Answer Incorrect Answer
    B Potential difference between any two points is the same Correct Answer Incorrect Answer
    C The electric field is directed tangentially along the wire Correct Answer Incorrect Answer
    D The loop cannot sustain current due to symmetry Correct Answer Incorrect Answer

    Solution

    In a conducting wire, current is driven by electric field , which points in the direction of current flow . Since the wire is bent into a loop, current must keep moving forward along the curved path. This means the electric field is tangential to the wire at each point to maintain the flow.

    • (A) Electric field cannot be zero ; otherwise, current wouldn't flow.
    • (B) If potential difference were same between any two points, current would not flow .
    • (C) Electric field inside the conductor is tangential to the wire at all points, driving current around the loop.
    • (D) A symmetric loop can sustain current ; symmetry doesn't prevent flow.
    Therefore, the correct answer is option (c).
