Which components did you use? Write their specifications.
The components used include:
LED - 5mm diameter, operates at 2-3V forward voltage, longer leg is positive (anode), shorter leg is negative (cathode).
Resistor - 220 ohms, limits current flow to protect the LED from the 9V battery.
DC Battery - 9V, provides electrical energy to the circuit.
Switch - controls the opening and closing of the circuit.
Breadboard - allows components to be connected without soldering.
Jumper wires - connect components on the breadboard.
Explanation
The chapter lists specifications for components: LED has two legs with the longer one being positive (anode) and shorter one negative (cathode). The 220 ohm resistor limits current. The 9V DC battery provides power. Breadboards have metal strips inside that allow connections without soldering.
