ID=(d q/d t)=(C d V/d t) When (d V/d t) is positive, ID is also positive.

Q. The displacement current flows in the dielectric of a capacitor when the potential difference across its plates

becomes zero

has assumed a constant value

is increasing with time

is decreasing with time

$I_{D} = \frac{d q}{d t} = \frac{C d V}{d t}$
When $\frac{d V}{d t}$ is positive, $I_{D}$ is also positive.

ID​=dtdq​=dtCdV​ When dtdV​ is positive, ID​ is also positive.

$I_{D} = \frac{d q}{d t} = \frac{C d V}{d t}$
When $\frac{d V}{d t}$ is positive, $I_{D}$ is also positive.
