A short circuit causes a drastic decrease in the ? of the circuit and could cause the ? to be dangerously high.

Explanation:
Short circuits create a path with very low resistance, so the overall resistance in the circuit drops dramatically. With the same supply voltage, current rises as resistance falls (I = V/R). That sharp increase in current can become dangerously high, risking overheating, component damage, or fire. So the resistance decreases and the current flow becomes dangerously high.
