Physics Concepts and References
Electricity
Ohm's Law Holt Physics by Serway and Faughn (c. 1999) Chapters 19 and 20
Must be comfortable with Ohm’s Law relating voltage, current and resistance
Understand combinations of resistors, series and parallel connections
Induced currents and Power Generation
Holt Physics by Serway and Faughn (c. 1999) Chapter 22
Faraday’s Law of Induction
http://hyperphysics.phy-astr.gsu.edu/hbase/electric/farlaw.html
Compute the power for simple generators by combining Faraday’s Law and Ohm’s Law
Thermodynamics Holt Physics by Serway and Faughn (c. 1999) Chapter 11
First Law of Thermodynamics
U = Q-W
Change in internal energy of system = Heat added to the system - Work done by the system
Four processes:
Isobaric - system stays at constant pressure. Work = Pressure* Volume Change = P V
Isothermal - system stays a constant temperature U = 0
Isovolumatric (Isochoric) - system stays at constant volume, W = 0
Adiabatic - no heat enters or leaves the system, Q = 0

Understand Cyclical processes on PV diagram
Work done equals area under the curve
Efficiency = 1 - Qc/Qh or 1 - Tc/Th Q is quantity of heat, T is temperature in Kelvin.
The subscripts refer to cold and hot reservoirs. Qc is waste heat. Qh is heat added to
the system.
