What Are The Disadvantages Of Heating Effect Of Current?

When an electric current is passed through a conductor, it generates heat due to the hindrance caused by the conductor to the flowing current. The work done in overcoming the hindrance to the current generates heat in that conductor. This phenomenon can be referred to as the heating effect of current.

Disadvantages of the heating effect of current

Following are the disadvantages of the heating effect of current:

1) When an electric current flows through the conductor, a part of it is converted into heat energy. This is a waste of energy.

2) The heat produced can damage the insulation and other electrical components, or even cause a fire

3) Reduces the life of several components in the circuit

4) An additional cooling system needs to be added to the circuit to counter the heating effect. This adds to the cost.
