Functions of the Electrical Components


               Electrical components have their own functions. Let’s see

               what their functions are.


                 I am a dry cell. My
                                                             Caution
                 function is to supply                       Caution
                 electrical energy.                       Bulbs are easily broken because

                                                          they are made of glass.




                                                             I am a bulb. My function is

                                                             to produce light.
