Question

Name any six domestic appliances based on the heating effect of electric current.

Answer 1

Hint: We know that the heating effect of electric current means utilized as working in electrical appliances. Most of the electrical appliances used in our houses. All bodies offer an amount of resistance to the flow of electric current. Thus resistance converts some amount of electric energy into heat energy. This is called the heating effect of current.

Complete step by step answer:
The materials which are good conductors of electric current will produce a very small amount of heating current. When the current flows through a high resistance more heat is produced. In some electronic devices, the production of heat will decrease due to its efficiency. But there are some electronic devices which have effective heating effect used are:
(i) Electric irons.
(ii) Electric water heaters.
(iii) Electric bulb.
(iv) Electric geyser.
(v) Electric fuse.
(vi) Electric stove.
(vii) Electric kettles and toaster.

Additional information: At homes, the electric current is used that is A.C., not D.C because large transformers are used to run transmission lines at high voltages in order to keep losses to a minimum. But the high voltage is dangerous, particularly to life, so bringing it into a house would not be an acceptable risk (because voltage does not go through zero).

Note: Advantages of heating effect of current:
(i) 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.
(ii) An electric bulb also exploits the effect.
Disadvantages of the heating effect of current:
(i) Sometimes, more heating can cause damage and may also cause fire.
