Alternator whine under load

Just wondering if it is normal to have an alternator whine/squeal when it's under a load? i.e.- when I have the A/C on, KC lights, etc.

It's just a high pitched whine that gets louder whenever I have accessories on. Nothing horrible but noticeable if you're standing next to the Jeep. Been that way on my Jeep for years and never really bothered me, just curious if it's normal. Thanks
