What is the short circuit current?

The short circuit current is simply a very large current that suddenly passes through the circuit that it cannot bear, and therefore the weakest point opens the circuit, and the reason for the passage of this very large current is due to the contact of two cables between which there is a slight voltage difference Its resistance is very small, and this means from Ohm's law that the current through the cable will be very large and this is the short circuit current.
