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:

Options

  1. ADisplacement current of magnitude equal to I flows in the same direction as I
  2. BDisplacement current of magnitude equal to I flows in a direction opposite to that of I
  3. CDisplacement current of magnitude greater than I flows but can be in any direction
  4. DThere is no current

Correct answer

A. Displacement current of magnitude equal to I flows in the same direction as I

Step-by-step solution

According to modified Ampere's law B . d l= ₀ (I_C+I_D ) For Loop L₁ I_C 0 and I_D=0 For Loop L₂ I_C=0 and I_D 0 Due to KCL I_C=I_D
