Lab: Setting Up A Breadboard

• My first try was a failure (Figure 1.1), as shown below, the bulb didn't light up. After watching the videos and texts on the websites, I realized that the reason for that was there was actually no electricity on the right side. So the yellow wire didn't work to connect.

• Then the second try succeeded. These two tries made me understand how the electricity flow works in the breadboard, and it helped a lot for the following experiments.

Make multiple bulbs work in parallel

Question 1:

For the parallel connection, it was obvious that the other two bulbs' lights were less bright than the other one. I assume that there was some energy lost in the parallel situation. As a result, I wonder if there are some solutions to increase the efficiency of the electric circuit.

Also, I would like to find out how to operate the circuit in series to reduce the use of wires and improve energy efficiency.

• Using a button to control the light

Question 2:

For the left image above, the connection was successful; however, for the right image, after I press the button, the red bulb's light was extremely small and I can't observe the green light with my eyes. I had no idea why that happened.

Switches

• Using multiple buttons to control different lights

The switches worked successfully. I was able to use different buttons to control different lights; also, I could press them together to make them light at the same time.

Question 3:
