Owing to skin effect:
Correct answer: B. portion of the conductor near the surface carries more current and core of the conductor carries less current
- A. current flows through the half cross-section of the conductor
- B. portion of the conductor near the surface carries more current and core of the conductor carries less current
- C. portion of the conductor near the surface carries less current and core of the conductor carries more cur¬rent
- D. any of the above
- E. none of the above
Explanation
Alternating current produces greater inductive opposition toward the conductor’s centre, so current crowds toward the outer surface. Thus, the surface region carries more current while the core carries less.
