Question

Statement I: Displacement current goes through the gap between the plates of a capacitor when the charge of the capacitor does not change.
Statement II: The displacement current arises in the region in which the electric field and hence the electric flux remains constant with time.

• A. If both statements are true and statement II is the correct explanation of statement I.
• B. If both statements are true but statement II is not the correct explanation of statement I.
• C. If statement I is true but statement II is false.
• D. If both statements are false.

Answer 1

Answer: (D)

Displacement current arises when electric field in a region is changing with time.
$I_{D}=\varepsilon_{0} \frac{d \phi_{E}}{d t}$
It will be so if the charge on a capacitor is not constant but changing with time.
