Almost all objects have an electrical charge, but which objects hold the charge the longest? This project looked at a 9 volt battery powering a LED and had a sensor detecting the electromagnetic fields of objects( Independent ). Many objects used in this experiment were all from the Triboelectric Series (human hair or hands, nylon, wool, etc.) and they were tested by rubbing objects on opposite ends of the Triboelectric Series and then determining which object held the charge the longest( dependent ). They were 3 trials which included 3 different objects (Cotton, Wool, Human Hair), the objects being rubbed against it and how long it takes for the LED to turn back on.
