Answers to the quiz.

1. The correct statement is Number 3.

2. From the left side of the breadboard, row no. 10 (five holes from A to E) is to the LED via its negative lead (cathode), and the ground bus (-) is connected to the LED via the resistor.

From the right side of the breadboard, row no. 10 (five holes from F to J) is connected to the LED via its positive lead (Anode), and row no. 15 (five holes) is connected to the LED via the yellow wire. The red wire is not connected to the LED at all.

3. The green wire is the correct one to connect the positive lead (anode) to the positive bus (+) on the breadboard.

4. Steps to connect two LEDs in parallel with a push button switch:

• Place the LEDs next to each other (both anodes (+) connected in one row and cathodes (-) in another row).
• Take a resistor (of the correct value) and connect the anodes (+) to the positive bus (+) via the resistor
• Connect one side of the push button to the cathodes (-), and connect the other side to the ground bus (-) via a jumper wire.
• Connect the power supply to your breadboard. Hurrah!
