Heating effect of electric current is both a blessing and a curse.
Advantages of Heating effect of current:
1. The heating effect of electric current is put to good use in room heaters and water heating coils where electricity is converted into heat energy.
2. An electric bulb also exploits the effect. The filament of the bulb is made of Tungsten metal, which glows when heated by the electric current flowing through it, thus giving out light.
3. An electric fuse also uses the heating effect of electric current. A fuse is rated for a specific amperage. When the current through it exceeds its rating, the heat produced melts the fuse wire thus opening the circuit.
Disadvantages of the Heating effect of current:
1. Wastage of energy during power transmission in overhead cables is a major disadvantage of the heating effect. To counter the ohmic losses, electricity is transmitted in a high voltage.
2. The heating effect reduces the life of several components in a circuit.
3. Additional cooling systems and heat sinks need to be added to circuits to counter the effect of heating, which adds to the cost.
