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).
