2.) How does hydrokinetic energy connect to circuits?
3.) How does hydrokinetic energy connect to magnets?
4.) How does hydrokinetic energy connect to electrical charges?
5.) How does hydrokinetic energy connect to the parts of waves?
Answer:
1.They generate power only from the kinetic energy of moving water (current).
2.relating to the motions of fluids or the forces which produce or affect such motions — compare hydrostatic.
3. It uses water motion to generate a high-pressure liquid rather than electricity.
4. tidal currents, ocean currents or river currents into electrical power.
5.When flowing water is captured and turned into electricity, it is called hydroelectric power or hydropower. There are several types of hydroelectric facilities; they are all powered by the kinetic energy of flowing water as it moves downstream.
