A fuse works by using a thin wire with a low melting point. When excessive current flows through the fuse, the wire heats up due to the heating effect and melts, breaking the circuit and preventing damage to appliances.

High-resistance materials, like nichrome, are used in electric heaters because they generate more heat when current flows through them. This is because the heat produced is directly proportional to the resistance of the material.

The heat produced in a conductor is proportional to the square of the current flowing through it, the resistance of the conductor, and the time for which the current flows. It is given by the formula H = I²Rt.

The heating effect of electric current refers to the phenomenon where heat is generated when an electric current flows through a conductor. This occurs due to collisions between electrons and atoms in the conductor.
