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:
  1. Displacement current of magnitude equal to I flows in the same direction as I
  2. Displacement current of magnitude equal to I flows in a direction opposite to that of $I$
  3. Displacement current of magnitude greater than I flows but can be in any direction
  4. There is no current

Solution


According to modified Ampere's law $\oint B . d l=\mu_0\left(I_C+I_D\right)$ 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 $\mathrm{KCL} \quad I_C=I_D$
