TEACHER CERTIFICATION STUDY GUIDE 123. Hoover Dam is perhaps the most famous hydroeletric dam in North America. Which on of the follwing best describes how Hydroelectric dams generate their power? (Rigorous) (Skill 5.18) Gravity imparts kinetic energy onto the falling water, which acts as a mechnical force turning the generator tubines. The turbines contain a coil of wire, and as the turbine spins it spins the coil of wire. This generates an electrical current in the wire that is then sent out to the power grid. Gravity imparts kinetic energy onto the falling water, which acts as a mechnical force turning the generator tubines. When the turbines spin they spin a series of electromagnets inside a coil of copper wire. This generates an electrical current in the wire that is then sent out to the power grid. Gravity imparts potential energy onto the falling water, which acts as a mechnical force turning the generator tubines. When the turbines spin they spin a series of electromagnets inside a coil of copper wire. This generates an electrical current in the wire that is then sent out to the power grid. Gravity imparts kinetic energy onto the falling water, which acts as a mechnical force turning the generator tubines. When the turbines spin they spin a series of permanment magnets inside a coil of copper wire. This generates an electrical current in the wire that is then sent out to the power grid.
