As seen in my physics lesson today.
The ammeter recorded a current of 0.00A, flowing through the circuit, even though the powerpack was on, and it had been turned up to about three quarters its maximum powerness; so I assumed no current was flowing.
I left my table momentarily to get a new powerpack, in the hope it would work this time; when I returned the length of wire I'd been testing the resistance of had singed a line through my physics book and was smoking.
Hmm....
[Incidentally, the voltmeter recorded that the p.d. across the wire was 0.00V as well. Hmm... again]
