This circuit is a digital circuit called an OR gate. The loose wires in the circuit act as inputs, and the LED is the output. The red wire is X input and the Y input is the yellow wire. The LED will be lite if both or either wire is receiving a 9v input. That is why the circuit is called an OR gate if either input is true then the gate opens. Digital circuits are circuits that have only two states, such as high-voltage/low-voltage, on/off, yes/no, and true/false.
 |
| X and Y have 9v inputs LED is on |
 |
| X has 9v input Y has no input LED is on |
 |
| X has no input Y has 9v input LED is on. |
 |
| X and Y has no input LED is off. |
