[Boatanchors] Choke Info Needed

[Price Smith]

A swinging choke is normally used between the diode and the first filter cap 
and the smoothing choke.
As the current increases, the inductance increases. The inductance only 
affects the ripple. As the ripple
decreases, the  effective voltage increases. Therefore with a resistive 
load, the current will increase.
