Hugely fundamentally ignorant question.

If I have an electronics device that claims to take a power adapter of 12V
200mA, and I plug in one rated at 12V 800mA, will the device merely draw the
proper 200mA (because the voltages are matched)?

Basically that's the idea.


Or is there something about PA's that can somehow force too much current
into a device?

See other posters' warnings about unregulated adaptors having a higher voltage
when only partially loaded.
