Electric Circuit

Project Number: 14

Description: Build the circuit shown and push the press switch (S2) to turn on the red LED (D1).

Educational Corner: What is really happening here? 1. The battery (B4, containing a 3.6V rechargeable battery with protection circuitry) converts chemical energy into electrical energy and "pushes" it through the circuit, just like the electricity from your power company. A battery pushes electricity through a circuit just like a pump pushes water through a pipe. 2. The snap wires (the blue pieces) carry the electricity around the circuit, just like wires carry electricity around your home. Wires carry electricity just like pipes carry water. 3. The press switch (S2) controls the electricity by turning it on or off, just like a light switch on the wall of your home. A switch controls electricity just like a faucet controls water. 4. The red LED (D1, a "light emitting diode") converts electrical energy into light; it is similar to the lights in your home. An LED shows how much electricity is flowing in a circuit just like a water meter shows how fast water flows in a pipe. 5. The base grid is a platform for mounting the circuit, just like how wires are mounted in the walls of your home to control the lights.
