Solution
Correct Answer:
Electric field in capacitor gap
Maxwell realized that Ampere's Law was incomplete for varying fields (like inside a charging capacitor).
- He introduced the Displacement Current (Id): Id=ϵ0dtdΦE
- This represents the effect of a changing electric field, which produces a magnetic field just like a real conduction current. This 'current' exists in the insulating gap of the capacitor, ensuring continuity of the total current.
This hard difficulty physics question is from the chapter electromagnetic waves, covering the topic of displacement current. It appeared in the 2025 exam.
