Chapter 29 - Maxwell's Equations and Electromagnetic Waves This is not a full chapter. You should know these equations already anyway: Maxwell's Equations 1. (gauss' law) 2. (gauss' law for magnetism) 3. (variant of Faraday's law) 4. (Ampère's Law) Note: displacement current ( ) - imaginary current from a capacitor when initially turned on. Creates a magnetic field just as if it was a wire. (the serves somewhat as an addendum to Ampère's law) Appendix Store the following values in your calculator using the "➔ sto" function Elementary Charge Coulomb's Constant Permeability of free space Remember also that you can get the permittivity of free space by coulomb's constant ( ) Reminder for Rebecca Karger: E+M topic breakdown for the test: 1. Electrostatics (ch. 21-23) 30% - charge, coulomb's law, gauss' law, electric field and potential 2. Capacitance (ch. 24) 14% - electric potential energy, capacitance, dielectrics 3. Circuits (ch. 26-27) 20% - current, resistance, power, steady-stable DC Currents, transients with capacitors (changing current). 4. Magnetic fields (ch. 26-27) 20% - force on moving charges and circuits, BiotSavert law, Ampère's law 5. Electromagnetism (ch. 28-30) 16% - Faraday's law, Lenz's Law, induction, Maxwell's Equations
