Q2. What's is Short Circuit how is the short circuit current calculated?
Ans. 
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...read more
