1 ans heating effect. Whenever an electric current flows through a wire (conductor), a small amount of electrical energy is converted into heat energy. This is called the heating effect of electric current. Heating effect is due to the resistance of the conducter
2 ans The strength of the induced current increased when the strength of the magnetic field increases. It will also increase when the number of turns is increased or if the speed of the conductor increases. 3 ans Practical Application
The heating effect of electric current is used in the following applications: Electric Bulb: In an electric bulb, the filament of bulb gives light because of heating effect of electricity. ... Electric iron: The element of electric iron is made of alloys having high melting point hope it will be helpful
