A short circuit occurs when a low-resistance path is established between points in a circuit that are normally at different electrical potentials. According to Ohm's Law (V = IR, or I = V/R), if the resistance (R) in a circuit decreases significantly while the voltage (V) remains relatively constant, the current (I) must increase dramatically.
At the time of short-circuit the current in the circuit,
