NEET 2024 — Physics solution

NEET2024Physics

A parallel plate capacitor is charged by connecting it to a battery through a resistor. If $I$ is the current in the circuit, then in the gap between the plates:

A
displacement current of magnitude equal to $I$ flows in a direction opposite to that of $I$ .
B
displacement current of magnitude greater than $I$ flows but can be in any direction.
C
there is no current.
D
displacement current of magnitude equal to $I$ flows in the same direction as $I$ .

Solution

Maxwell's displacement current $I_{d} = ε_{0} \frac{d Φ _{E}}{d t}$ equals the conduction current $I$ in magnitude and direction, ensuring continuity of current around the circuit even across the capacitor gap.
