1. Mr. Fleming

2. D. 7 Explain how heat is used to generate electricity.

3. How is electricity generated? What are energy transformations in steam generated power plants?

4.  A conductor moved across a magnetic field and an electric current is produced. ◦ Two ways this can happen  Magnets move around conductor  Conductor moves across magnetic field of magnet.

6.  Electromagnetic Induction Electromagnetic Induction The process of generating an electric current from the motion of a conductor through a magnetic field.

7.  An electrical generator converts mechanical energy into electrical energy.  Steam and nuclear powered plants do this on a large scale. ◦ Produce enough electricity to provide for energy needs of society.

8.  A fossil fuel is fed into a boiler and burned. OR  Uranium atoms are split in a nuclear fission reaction to produce heat.

9.  Water is piped into the boiler and heated, turning into steam.

10.  Steam travels at high pressure through steam line.

11.  The high pressure steam turns a turbine, which spins a shaft.  Turbines- a circular device made up of many blades that move in a circular motion when force is applied. ◦ Flowing water from dam, wind, steam from the burning of fuels, and even the ocean’s tides can be used to turn turbines.

12.  Inside the generator, the shaft spins coils of copper wire inside a ring of magnets. This creates an electric field, producing electricity.

14.  Electricity is sent to a switchyard, where a transformer increases the voltage, allowing it to travel through the electric grid.

15. How do you generate electricity? Pass wire through magnet or magnets or around magnet. Electrical generators convert __________ energy to __________ energy. Mechanical, Electrical

16.  In a steam powered plants ________________ energy is converted into ________________ energy. Heat (Thermal), Electrical
