Inside the generator is a rotor and turbine pieces of metal in the turbine magneticallyalong with a circuit inside, which can transfer the induces an electric field via the copper coil toelectricity produced by the generator from AC to generate electricity. Finally, the whole generatorDC. The maximum voltage and power output will has a flexible elastic piece at the nozzle entrancebe 5V and 10 Watts. which

Tools.Piezoelectric ChargingPiezoelectric energy was experimentally discovered by Pierre and Jacques Curie in the 1880s.They discovered that when mechanical stress is applied to certain materials, charges are displaced,and materials produce voltage under mechanical stress.3 We harness the energy of human walkingmovement by placing piezoelectric elements under the foot so that energy is produced with eachstep.When mechanical strain is applied to the piezoelectric elements, the crystals produce alternatingcurrent (AC). For a battery to charge, it requires direct current (DC). We used rectifying circuit sothat the current can only flow away from the piezoelectrics.4Furthermore, because the mechanical strain of walking does not provide constant pressure

modern physics.The circuits material begins with DC circuits, transitions to AC circuits, and finalizes withtransformers and electrical power transmission. The waves section consists of mechanical, sound,and electromagnetic waves. Wave interference, the Doppler effect, and Young’s double-slitexperiment are also examined. In fluids, the students learn about Bernoulli’s, Pascal’s, andArchimedes’ principles. The last section of modern physics consists of the photoelectric effect,Compton scattering, lasers, and De Broglie wavelength.United States Military Academy (USMA) History, Digital Collections, and Unique ResourcesThe Unique Resources of the U.S. Military Academy Library include documentation of the historyof West Point and its alumni.
