For a purely inductive or a purely capacitive circuit, the power factor is
zero
0.5

$\infty$
Solution
$P=V_{r m s} I_{r m s} \cos \phi$
Here, $P$ is the power factor, $V_{r m s}$ is the root mean square value of voltage,
$I_{r m s}$ is the root mean square value of current and $\phi$ is the angle between the voltage and the current.
$\Rightarrow P=V_{r m s} I_{r m s} \cos 90^{\circ}$
$\therefore P=0$
Therefore, the power factor of pure inductor and pure capacitor circuit is zero.
