NEET Physics Maxwell's Equations MCQ Question
Consider a parallel plate capacitor connected to a time-varying current. Describe a situation where the electric field between the plates is changing with time. Which of the following best explains the nature of the current within the capacitor?
The capacitor has only displacement current because the conduction current does not reach the space between the plates.
The capacitor has only conduction current because the displacement current does not exist.
Both displacement and conduction currents are present within the capacitor.
Neither displacement nor conduction current is present in the capacitor.
Correct Answer
Detailed Explanation
Inside the capacitor, there is no conduction current, i.e., i_c = 0, and there is only displacement current, so that i_d = i, as per the NCERT context.
