The chapter will delve into the heating effect of electric current and its practical applications.

The chapter will address the constituents of electricity, electric circuit flow, and factors regulating current.

The Joule heating in the fuse melts it, breaking the electric circuit and preventing the flow of unduly high electric current.

Overloading occurs when the live and neutral wires come into direct contact, causing a short circuit. The consequence is a sudden increase in current.

An electric fuse is crucial in domestic circuits as it prevents damage to appliances and the circuit caused by overloading or short circuits. It acts as a safety device by breaking the circuit when excessive current flows, safeguarding against potential ...
