Question

When does an electric short circuit occur ?how can it be prevented

Answer 1

Answer:yes by using a fuse of accurate current rating or a MCB

Explanation: An electric short circuit occurs when the live wire gets in contact of neutral wire... Actually the word shortcircit mean the current flows through a short way instead of the complete circuit as a result a huge amount of electric passes at a time

Answer 2

hi mate..

first you want to know that how an electric short circuit occur so mate a short circuit is when there is a low resistance connection between two conductors that are supplying electrical power to a circuit.

so mate this would generate an excess of voltage streaming and cause excessive flow of current in the power source. The electricity will flow through a 'short' route and cause a short circuit.

for a prevention you want to do to prevent the effects of a short circuit a fuse is used. ....... A more modern version is an automatic "fuse", mate this fuse help us by which is a switch that turnes the power off at a certain current, but that can be reset ...of course, after the problem is solved...

i hope mate it helpfull to you
