This weekend as I was cleaning my room, I needed to unplug my lamp to plug in the vacuum cleaner. However, I forgot to turn off the light before I unplugged the wire. When I did so, a spark was formed. I realized that I failed to complete the circuit and the spark was the circuit breaking. This could be dangerous because if my hand was near the outlet, I could've been zapped. This surge of energy is kind of like the energy released by a capacitor when it is being discharged. I probably would've felt the same shock that I felt as I touched the three buttons on the camera.
