NEETPhysicsMoving Charges and MagnetismMCQ+4 / −1

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

  1. A
    There is no current
  2. B
    Displacement current of magnitude equal to III flows in the same direction as III
  3. C
    Displacement current of magnitude equal to III flows in a direction opposite to that of III
  4. D
    Displacement current of magnitude greater than III flows but can be in any direction

Correct answer: B

NEET 2024 Physics - Moving Charges and Magnetism Question 5 English Explanation

According to modified Ampere's law

$$\oint B \cdot d I=\mu_0\left(I_C+I_D\right)$$

For Loop $L_1 \quad I_C \neq 0$ and $I_D=0$

For Loop $L_2 \quad I_C=0$ and $I_D \neq 0$

Due to $$\mathrm{KCL} \quad I_C=I_D$$
