When something has been effected, it's been brought about. If you're responsible for an effected change, you've made it happen.

If you know that when choosing between affect and effect, effect is almost always a noun, then you'll appreciate that effected is a bit of a rare bird. The verb form of the "e" word means "to bring about," and it can act as an adjective in its -ed form: "The effected change in the garden while I've been away is far beyond what I'd hoped."
