hello..
Can resistors cause a short-circuit?

Particularly in a powersupply?
The reason i ask is that because i'm fixing one. From my thinking
resistors are put in a circuit to give resistance unless they change?
I have seen resitors blown but thats considered high
resistance(infinit)because the resitor is basically gone and thats not
a short circuit i'm talking about. A short circuit resistor is where a
resitor would let most of the current through hence creating a short
circuit situation is this common or even possible.

Thanks
