  1. Series and Parallel Circuits Parallel circuit: Voltage is the same in all elements (Currents add) Series circuit: Current is the same in all elements (voltages add)

  2. US Electrical power Look at the text, which Shows an interesting Distinction between Utility producers and Non-utility producers In terms of this mix. (p 319) http://www.eia.doe.gov/fuelelectric.html http://www.eia.doe.gov/cneaf/electricity/epa/epat4p1.html see for Information on actual energy consumed by fuel type.

  3. US Electrical Power Generation

  4. North American Power Plants http://en.wikipedia.org/wiki/Electric_power_transmission Another interesting site: http://carma.org/ will give you more info on these Plants (and indeed 50,0000 others worldwide!).

  5. US Electrical power http://www.eia.doe.gov/cneaf/electricity/epa/epa.pdf#page=15

  6. Possible topics for last 2 weeks(votes on first day of class) • Global warming (class discussion). • Nuclear Power (fission/fusion) (24) • Hydrogen economy (Fuel Cells) 22) • Fuel Cells (11) • Unconventional Fossil (9) • Increasing efficiency; appliances, lights, etc. • Electrical Grid

  7. Faraday’s Law • “A coil of wire experiences an electro-motive force that is proportional to the rate of change of the magnetic flux passing through the loop.” • Magnetic flux is the product of the magnetic field strength times the area it passes through projected onto the field direction (just like solar flux on a panel).

  8. Typical generating station http://www.wvic.com/how-gen-works.htm Web site also has a good schematic of a generator in action

  9. Typical Steam generator

  10. U. Cincy Cogeneration Plant Annually produces: 245M kWh Heat to 9Msq.ft of bldg space http://www.uc.edu/facmgmt/utility.asp

  11. Combined Cycle plants http://www.cogeneration.net/Combined_Cycle_Cogeneration.htm

  12. Combined cycle/Carbon sequestration plant http://alt-e.blogspot.com/

  13. Electrical distribution/transmission

  14. Transmission/distribution lines Some High Voltage transmission lines are DC not AC (see right), but they look pretty much the same. http://www.osha.gov/SLTC/etools/electric_power/illustrated_glossary/transmission_lines.html
