system
In the rectangular coordinate system $(xOy)$, the parametric equation of line $l$ is $ \begin{cases} x=1+t\cos α \\ y=t\sin α \end{cases} (t$ is a parameter, $0\leqslant α < π)$, and a polar coordinate system is established with the coordinate origin as the pole and the non-negative semi-axis of $x$ as the polar axis. The polar equation of circle $C$ is $ρ=-4\cos θ$, and the distance from the center of circle $C$ to line $l$ is $ \dfrac {3}{2}$.
(I) Find the value of $α$;
(II) Given $P(1,0)$, if line $l$ intersects circle $C$ at points $A$ and $B$, find the value of $ \dfrac {1}{|PA|}+ \dfrac {1}{|PB|}$.
