Question

What are the disadvantages of the heating effect of current?

Answer 1

Heating effect of current

Whenever an electric current flows over a conductor, heat is generated attributable to the conductor's impedance towards the running current.

Some disadvantages are provided below:

1. A portion of the electric current that travels through the conductor has been transformed into heat energy. This seems to be an inefficient use of energy.
2. To counteract the heating impact, an extra cooling system must be added to the circuit. This raises the price.
3. The heat generated can harm the insulation and other electrical components, as well as catch on fire.
4. Reduces the endurance of various circuit elements.
