EFFECTS OF ELECTRIC CURRENT:

            1.  HEATING EFFECT OF ELECTRIC CURRENT:
                     When an electric current is passed through a conductor, the conductor becomes hot

                       after some time and produce heat.
                     This happens due to the conversion of some electric energy, passing through the

                       conductor, into heat energy.

                     This effect of electric current is called Heating effect of electric current.
                     E.g. Filament bulbs, Fluorescent lamps, electric cookers, electric kettles and electric

                       irons.
            2.  MAGNETIC EFFECT OF ELECTRIC CURRENT:

                     When an electric current passes through a conductor, it produces a magnetic field

                       around it, and behaves like a magnet.
                     The magnetic field produced can be detected by placing a magnetic compass near

                       the conductor, where the magnetic needle shows deflection.
                     E.g. Electromagnets used in electric bells.

            3.  CHEMICAL EFFECTS OF ELECTRIC CURRENT:

                     The chemical changes which take place in conducting liquids on passing electric
                       current through them are called chemical effects of electric current.

                     E.g. electroplating used in polishing of artificial jewellery, zinc coating to protect iron
                       utensils from rusting.
