A wire's diameter decreases linearly from d_i to d_f = d_i/2. If the wire has a current of I at the end whose diameter is d_i, then the current at the end whose diameter is d_i/2 A) decreases by a factor of 2. B) increases by a factor of 2. C) decreases by a factor of 4. D) remains the same.

Question

Quizplus · Accepted Answer

The current flowing through a conductor is independent of its cross-sectional area, meaning it remains constant regardless of changes in the wire's diameter.
