Question

what are the disadvantages of heating effect of current

Answer 1

The heat is a product of resistance to the flow. Energy will be consumed to overcome the resistance, producing the heat, which in turn increases the resistance, leading up to a runaway situation of excess heat being produced at the expense of the power to the circuitry. If the heat cannot dissipate then fire or circuit failure may result.

Answer 2

Hlo friend, here is your answer.


When an electric current passes through a wire, it gets heated up. This is known as 'heating effect' of electric current.


There are, however, some serious practical disadvantages of the heating effect of current. When electricity is transmitted from the generating stations to the consumers, the heat produced in the transmitting wires gets wasted as it is simply radiated into the atmosphere. This is an unwanted loss of electrical energy. We, of course, adopt ways and means to minimize this loss. The heating effect of electric current is also capable of breaking the insulation of different wrings/devices.

Hope it helps you.
