    Concept

                        • Switch Control: The switch is used to open and close the connection.

                        When it’s ON, power from the battery goes to the LED and makes it
                        light up. When it’s OFF, the power stops, and the LED turns off.

                        • Battery Power: The battery provides the energy needed for the LED to
                        light up.

                        • LED  Lighting:  When  everything  is  connected  properly  and  the

                        switch  is  ON,  the  LED  will  light  up,  showing  how  energy  is  used  to
                        create light.

                     Observation

                     When you turn the switch ON, the LED will light up, showing how the

                     battery is powering the LED. When you turn the switch OFF, the light goes
                     out because the connection is stopped. This helps us see how a switch

                     controls the power to the light.

                     Application

                     This is similar to how a room light works.
                     When  you  press  the  light  switch,  the

                     bulb turns on, and when you turn the
                     switch off, the light goes out.

                                                                                      Understanding the Circuits   41
