NEET Physics (general) MCQ Question
Which of the following statements about the displacement current and magnetic fields in electromagnetic waves are correct?
Inside a capacitor, the conduction current is zero and the displacement current is equal to the total current.
Outside the capacitor plates, the displacement current is present while the conduction current is zero.
The displacement current can create a magnetic field in regions where the conduction current is absent.
The displacement current is always greater than the conduction current in all scenarios.
Correct Answer
Detailed Explanation
Inside a capacitor, the conduction current is indeed zero, and the displacement current equals the total current flowing through it. Outside the capacitor, there is only conduction current and no displacement current, which is a key aspect of Maxwell's correction to Ampere's law.
