Question

What are the disadvantages of the heating effect of current?

Answer 1

Hint: The present when flows through any conductor produces a heating effect. This heat produced can't be utilized in the least places, rather it damages the circuits causing heat and melting of other materials can cause damage.

Complete answer:
When an electrical current is skilled in a conductor, it generates heat thanks to the hindrance caused by the conductor to the flowing current. The work wiped out overcoming the hindrance to the present generates heat therein conductor. This phenomenon is often mentioned because of the heating effect of current.

Following are the disadvantages of the heating effect of current:
1) When an electrical current flows through the conductor, a neighborhood of it's converted into heat.This is often a waste of energy.
2) the warmth produced can damage the insulation and other electrical components, or maybe cause a fireplace.
3) Reduces the lifetime of several components within the circuit.
4) a further cooling system must be added to the circuit to counter the heating effect.

Following are a couple of advantages of the heating effect of current:
1) The heating effect of current is employed in heating appliances like electric iron, room heaters and water heaters.
2) an electrical fuse is a crucial application of the heating effect of current. The working rule of the fuse is predicated on the heating effect of current.
3) they're also utilised in electric bulbs and electric lamps to supply light.

Note: When current is supplied to a purely resistive conductor, the energy of electrical current is dissipated entirely within the sort of heat and as a result, the resistor gets heated. The heating of a resistor due to dissipation of electricity is usually referred to as the heating effect of electrical Current.
