    Output

                      In this activity, you will create a simple working circuit using an LED light, a
                      battery, a resistor, and a switch. When the switch is turned on, the LED will
                      light up, showing how electricity flows through the circuit to make the light

                      work.  This  activity  will  help  You  understand  how  everyday  electronics,  like
                      lights, work.

                      Concepts

                      1.  Electricity  and  Circuits:  You  will  learn  how  electricity  flows  through  a

                         circuit to power things like lights. The battery provides the energy, and the
                         LED (light) turns on when the switch is flipped. This is how many things in
                         our homes, like lights and toys, work.

                      2.  The Role of a Resistor: The resistor helps control the amount of electricity

                         flowing to the LED, so it doesn’t get too much energy. It keeps the LED safe
                         from burning out, teaching You that sometimes we need to slow down the
                         energy in a circuit.

                      Observations

                      During the “Creating a Working Circuit” activity, You will observe how the LED
                      light turns on when the switch is flipped, and the circuit is completed. You will
                      notice:

                         • The LED lights up when electricity flows through the circuit.

                         • The resistor makes sure the light works safely without too much energy.

                         • The switch controls the flow of electricity, turning the light on and off.

                      Application

                      Have you noticed that when we press the switch,
                      the  light goes on  and off.  When  we  press the
                      switch, it completes the circuit and allows current

                      to  flow  through  it  which  results  to  turn  on  the
                      light and when we press the switch again it breaks

                      the circuit due to which current doesn’t passes
                      through it hence light turn off.
