1 Exam 3 Review Session I will hold a review for Exam 3 which covers Chapters 27, 28, 29 and 30, on Wednesday November 7 th at 7:15pm in MPHY 205. Exam 3 will be given in class on Thursday, November 8 th. November 6, 2012 Physics 208 1
2 Inductance Chapter 30 November 6, 2012 November 6, 2012 Physics 208 2
3 Learning goals for Chapter on Inductance How a time varying current in one coil can induce an EMF in a second coil. How to relate the induced EMF in a circuit to the rate of change of the current in that circuit. How to calculate the energy stored in a magnetic field. How to analyze circuits that include both a resistor and an inductor. Why electrical oscillations occur in circuits that include both an inductor and a capacitor. Why oscillations decay in circuits with an inductor, resistor and capacitor. November 6, 2012 Physics 208 3
