Basically, you can think of a shortcircuit as taking a branch with a single resistor R, and doing R → 0. From V = IR, you see that I = V/R, so if R → 0, the only way to stop I from going to infinity and being a defined finite value, is to have V = 0, that is, the potential difference across a shortcircuit vanishes.

If Votherthan 0, that's when you should be worried.

The I of my example would be extrapolated to whatever it need be, per particular circuit.
