It depends on the type of shorts. If high current source shorted with zero ohms most like it will burn the trace but with lower ohm shorts it may just lower the voltage.

If a circuit is shorted, then ideally, current and voltage should be infinite and zero respectively. But in practical, the voltage value gets reduced.
