Abstract
Potential energy is stored in water (in falling water) and kinetic energy (in flowing water) so that many studies have used water as alternative energy. This research was conducted to investigate the electric voltage generated by the waterwheel with different water flows and water levels. How to make a waterwheel are: (1) Prepare tools such as a plastic wheel, dynamo type (5V), cables, and lamps. (2) Connect the end of the plastic wheel to the end of the rotating dynamo. (3) Connect the cables to both ends of the dynamo. (4) Connect the two free ends of the cable to the lamp. (5) Test the waterwheel on running water and connect the cable to the multi-tester if you want to measure the voltage and current. The method used in this research is a demonstration experiment. The results of the study indicate that the electric voltage caused by the rotation of the wheel by running water can turn on the light. The greater the flow of water that flows, the greater the voltage generated and the lights get brighter. Furthermore, the experiments in this study can be used for the science learning process to students.
