• Blue

• Brown

On which row is the input wire placed on the breadboard?

• Row 6

• Row 7

• Row 8

• Row 9

Where is the output wire connected on the breadboard?

• F7

• G9

• J17

• J23

What is the purpose of the resistor in the circuit?

• To connect the LED

Where is the long leg of the LED placed on the breadboard?

• Row 23

• Row 17

• Row 7

• Row 26

What happens when the slide switch is set to zero?

• The LED lights up

• The circuit is incomplete

• The LED remains off

• The resistor is bypassed

What should you do if the circuit does not work with a constant power supply?

• Rewire the breadboard

• Replace the LED

• Check the resistor

• Switch to portable batteries
