The correct answer is:
Decreases in the first circuit and increases in the other
For the first circuit $i=\frac{V}{Z}=\frac{V}{\sqrt{R^2+\omega^2 L^2}}$
$\therefore$ Increase in $\omega$ will cause a decrease in $i$.
For the second circuit $i=\frac{V}{\sqrt{R^2+\frac{1}{\omega^2 C^2}}}$
$\therefore$ Increase in $\omega$ will cause an increase in $i$.
$\therefore$ Increase in $\omega$ will cause a decrease in $i$.
For the second circuit $i=\frac{V}{\sqrt{R^2+\frac{1}{\omega^2 C^2}}}$
$\therefore$ Increase in $\omega$ will cause an increase in $i$.
