How dams make electricity? An impoundment facility, typically a large hydropower system, uses a dam to store river water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity.
How do dams generate electricity? The dam stores lots of water behind it in the reservoir. … Gravity causes it to fall through the penstock inside the dam. At the end of the penstock there is a turbine propellor, which is turned by the moving water. The shaft from the turbine goes up into the generator, which produces the power.
Can dams be used to make electricity? Large scale hydroelectricity projects typically involve dams. Run-of-river and tidal projects also harness the power of moving water to generate renewable electricity. … As the water flows down through the dam its kinetic energy is used to turn a turbine.
Do I need a converter to charge my phone in Europe? If your equipment has a transformer, as all Smart Phones, Computers, and tablets have, you don’t need a converter – the voltage is converted by the transformer. European Voltage is usually 220, and the US is 110. So things without a transformer need a converter.
