hello..
Can resistors cause a short-circuit?

Particularly in a powersupply?

Mikuz-

A short circuit in a resistor is certainly possible. However it would be
extremely unusual unless its voltage rating was exceeded, resulting in a
dielectric breakdown.

Is it a new supply? I've seen wrong-value resistors in circuits go
unnoticed because of off-color bands or illegible markings. Such a power
supply might appear to be OK prior to a delayed failure caused by the
wrong-value resistor.
