Electricity Flashcards
How does hydroelectric powerplant work?
PE is converted to KE as the water flows down to the turbine from the reservoir. The turbine turns and generates electricity.
What is static electricity?
it occurs when electrical charges build up on a material’s surface
What is dynamic electricity?
the flow of electric charges in a circuit
What are the disadvantages of hydroelectric energy
it harms wild-life and a high-cost
How does geothermal energy work?
Heat from the mantle warms water that has seeped into the reservoir, when the water becomes hot enough it will break through the earth’s surface as steam or hot water
How does wind energy work?
The wind turns the blades of a turbine which spins a generator and creates electricity.
What is the transmission system in order?
powerplant, step-up transformer, high-voltage transmission line, step-down transformer
What is the conversion of energy in a generator
Mechanical energy to Electrical energy
