Joule’s heating is not always desirable.
EXPLANATION:
Joule heating is the process in which electric energy is converted to heat energy. The electric current flows through a resistor and this gets converted to heat energy in Joule heating. If Joule heating is always used, excess of heat can be generated that can cause damage.
Take for instance electrical appliances. If the electric appliances are always heated using Joule’s heat, the excessive heat generated will cause damage as it may lead to an electric short circuit.
