how does shot circuit forms? what are its effect?​

Answer 1

$How \: does \: shot \: circuit \: form \: ?$

• A common type of short circuit occurs when the positive and negative terminals of a battery are connected with a low - resistance conductor , like a thin wire .

• With a low resistance in the connection , a high current will flow , causing the delivery of a large amount of energy in a short period of time .

$What \: \: are \: \: it's \: \: effects ?$

• When a short-circuit occurs, the current in the system increases to an abnormally high value while the system voltage decreases to a low value .

• The heavy current due to short - circuit causes excessive heating which may result in fire or explosion .

Answer 2

→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. Thus, the decrease in value of resistance of the circuit raises the current to a significant amount. As a result, the wires become hot and sparks are caused by Joule's heating effect of current
