Engineering Are RLE Load and Capacitive Load Buck Choppers Identical?

[McMurry]

Homework Statement

I've gone through two different books... and both give a different circuit for the buck chopper.
Is the one with RLE load is totally same like the one with a capacitor in parallel with the resistive load?
