In this experiment, I built a simple electrical circuit using a battery, wires, a lightbulb, a paper clip, and a piece of cardboard. Before starting, I only had a basic understanding of how circuits worked—I knew electricity needed a closed loop, but I had never built one myself. As I set everything up, I ran into some trouble with the connections, and the lightbulb didn’t turn on right away. After checking and adjusting the wires to make sure everything was connected properly, the bulb finally lit up. That moment felt exciting and rewarding. It helped me clearly see how electricity flows through a complete circuit and made the concept feel much more real. This hands-on experience also taught me how important it is to have solid, secure connections, and it gave me more confidence in working with basic electronics in the future.
