define overload, short circuit and fuse
Answers
Answer:
An electric overload occurs when too much current passes through electric wires. The wires heat and can melt, with the risk of starting a fire.
A short circuit is an electrical circuit that allows a current to travel along an unintended path with no or very low electrical impedance. This results in an excessive current flowing through the circuit.A short circuit is an electrical circuit that allows a current to travel along an unintended path with no or very low electrical impedance.

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.
Answer:
Short circuit occurs when there is a fault between the line to earth. Overload occurs when equipment draws excess current from the supply. A short circuit usually takes place when neutral and live wire touch each other. Overload occurs when the number of devices joint in a single socket are more.
