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?
