1. Chapter 30 Inductance, Electromagnetic Oscillations, and AC Circuits

2. Mutual Inductance In what general situations does mutual inductance occur? (Sketch it out) The quantity Mutual Inductance, M 21, can be considered a proportionality constant between what two quantities? How are the emfs related to mutual inductance in each circuit derived, and what are they? What maximizes mutual inductance?

3. Self-Inductance In what general situation does self- inductance occur? (Sketch it out) The self-inductance, L, can be considered a proportionality constant between what two quantities? How is the emf in the circuit related to self- inductance derived, and what is it? What is the circuit diagram symbol for self- inductance?

4. Self-Inductance (cont’d) How is the self-inductance figured out for a few simple cases?

5. Energy in a B-field What is the work done to increase the current from zero to I in an inductor with inductance L? Why does this make sense? What is the energy density in a magnetic field? Why does this make sense?

6. LR Circuits What is a simple LR circuit? What equation governs its behavior? What is its behavior (in words, graphs, mathematically)? If L is analogous to mass, what physical situation is analogous to an LR circuit?

7. LC Circuits What is a simple LC circuit? What equation governs its behavior? What is its behavior (in words, graphs, mathematically)? If L is analogous to mass, what physical situation is analogous to an LC circuit?

8. LCR Circuit What is a simple LCR circuit? What equation governs its behavior? What is its behavior (in words, graphs, mathematically)? If L is analogous to mass, what physical situation is analogous to an LCR circuit?

9. Resonance in an LCR Circuit In what way can resonance occur in an LCR circuit? How is this resonance analogous to resonance of a damped, driven harmonic oscillator?
