Think of it sort of in the context of Star Wars. Sometimes the scene is one character in one place, like Luke standing with Ben by the sand crawler, and then there's a wipe and the next scene is Luke arriving at his home. Sometimes it's a change from one character to another, like the scene change from the Falcon escaping the Death Star to Vader and Tarkin talking about them getting away.
In some cases, these scenes, especially if they're long, can take up an entire chapter. Other times, this is where you see a line/space break--a single line of space between paragraphs--indicating a change. Star Wars is a good example of this, especially if you look through the novels. Early on, in both movies and novels, you'll get longer scenes with one character--sometimes there's a location change, sometimes there's not--and usually the change comes at the end of the chapter when you switch POVs. The scene changes get smaller and quicker as you get closer to the end-book or movie-and the switches happen multiple times in a chapter. Sort of like the Battle of Yavin at the end of SW--each POV switch--from Luke to Han to Leia to Vader--can each be a different scene, but overall they'd be in the same chapter.
This may or may not make sense. I would've used Dresden as a reference, but none of the books are close to hand. And I'm pretty sure that, for the most part, each chapter tends to be a self-contained scene.
