if you put it in a lamp it can probably sense resistance to the switch. If the power is out and it is plugged in and the switch is on there will be a measurable difference in the resistance from the bulb and the socket
absolute crap, if its got a built in battery it doesnt need to be plugged in

So it's plausible it can tell the difference between turned off and power out?

Re: So it's plausible it can tell the difference between turned off and power out?
since I answered off the top of my head I thought I should check a few things https://www.quora.com/How-do-I-find-the-electrical-resistance-between-the-two-leads-of-my-110-volt-wall-outlet-at-home If you have a doubt about the wiring being faulty or something and hence you want to measure the resistance then.maybe a real electrical engineer can give a better answer.
