NEET Physics (general) MCQ Question
Which of the following statements regarding the behavior of electric and magnetic fields in electromagnetic waves is correct?
Inside a capacitor, the electric field contributes to the displacement current but not the conduction current.
Magnetic fields can exist in regions where there are no electric fields present.
The direction of the electric field is always parallel to the direction of wave propagation.
The displacement current can only exist outside the capacitor plates.
Correct Answer
Detailed Explanation
Inside a capacitor, there is no conduction current, and thus the displacement current is responsible for the electric field's behavior, as stated in Chunk 1. This indicates that the electric field contributes to the displacement current only within the capacitor.
