What's is Short Circuit how is the short circuit current calculated?

Question

Accepted Answer

Short circuit is an abnormal connection between two nodes of an electric circuit that results in excessive current flow.

Short circuit occurs when a low-resistance path is created between two points in an electrical circuit.
Short circuit current is calculated using Ohm's Law: I = V/R, where I is the current, V is the voltage, and R is the resistance.
Short circuit current can also be calculated by dividing the voltage by the total impedance of the circuit.
Short circuit current is important for determining the rating of circuit breakers and protective devices.
Example: If a circuit has a voltage of 120V and a resistance of 2 ohms, the short circuit current would be 60A.
