Question

explain short circuit and fuse​

Answer 1

Answer:

$\huge\mathbb \green{ANSWER}$

A short circuit is an abnormal connection between two nodes of an electric circuit intended to be at different voltages. This results in an electric current limited only by the Thévenin equivalent resistance of the rest of the network which can cause circuit damage, overheating, fire or explosion.

Answer 2

Answer:

A bad electrical connection that causes a machine to stop working is called short circuit.

A fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current.
