Options
- A. Displacement current of magnitude equal to I flows in the same direction as I
- B. Displacement current of magnitude equal to I flows in a direction opposite to that of I
- C. Displacement current of magnitude greater than I flows but can be in any direction
- D. There is no current
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 L_1 I_C 0 and I_D=0 For Loop L_2 I_C=0 and I_D 0 Due to KCL I_C=I_D
