How does short circuit from? what is its effect?
Answers
Answer:
Short circuit occurs when naked live and neutral wires touch each other. In such situations, the resistance of the circuit becomes very less. Now, according to Ohm's law, current is inversely proportional to resistance. ... As a result, the wires become hot and sparks are caused by Joule's heating effect of current.
Answer:
When live wire comes in contact with natural wire a large amount of current flows through it leading to short-circuiting. This resistance of circuit becomes very small thus a large number of current flows leading to the production of a large amount of heat thus may cause electric fires. This may cause electric fires. This may damage our electrical appliances. We can also get electric shock thus short-circuiting is dangerous.
