Options:
  • A \( 1.8 \times 10^{-8} \mathrm{C} \mathrm{s}^{-1} \)
  • B \( 3.6 \times 10^{-8} \mathrm{C} \mathrm{s}^{-1} \)
  • C \( 4.1 \times 10^{-11} \mathrm{C} \mathrm{s}^{-1} \)
  • D \( 5.7 \times 10^{-12} \mathrm{C} \mathrm{s}^{-1} \)

The correct answer is: \( 1.8 \times 10^{-8} \mathrm{C} \mathrm{s}^{-1} \)
Given that,
dqdt=1.8×10-8 
the displacement current is
Id=dqdt Id=1.8×10-8 C s-1
