Short circuit KVA(MVA) divided by % impedance. At the time of short circuit , the current will be very high due to short circuit impedance or resistance which will be very small or Zero
The short circuit current is infinity because the resistance at this circuit is Zero
by ohm law ..becouse the volte and impdans is low
MVA Method is an easy way to find short circuit Calculations. Compared to other methods that are Ohmic and Per Unit Methods. The conversion formulas used for both these methods are complex and not easy to memorize.
The calculating procedure for an example network is mentioned below please have a look

Thanks for asking;
When short circuit occurs, the resistance of the circuit becomes zero allowng maximum current to flow through as there is no obstruction to electron flow
The Whole current passes through the short circuit .The current before that node is the current passes trough that short circuit.
It can be calculated using Ohm's law.
Short Circuit Current is immensely high current which arises the need of its calculation to be in large unit such as Kilo Amps, there are number of ways to calculate short circuit current one of the method is by evaluation of " M " Multiplier factor and " f " factor where M = 1 / 1+ M ,
f = 1.7 X Length of conductor X Current at beginning of Ckt / no. of conductors X Conductor Constant X Voltage
And so Short Ckt Current = I s.c = current at beginning X M
find out the resistance of short circuit and applied voltages then use ohm's law to find the short circuit current.
the short circuit current are in kilo ampares because there are low resistance in short circuit so low opossition to the flow of current
