Covers 27-33 + lecture, lab, discussion, HW
8 1/2 x 11 handwritten note sheet (both sides) allowed
Topics • 27 Electric Field: The electric force field is associated with
static charge.
• 28 Gauss’s Law: Electric field flux is conserved.
• 29 Electric Potential: Electric work implies potential energy
• 30 Potential and field: Capacitors store electric energy.
• 31 Current and Resistance: Steady current density follows electric field in simple circuits.
• 32 Fundamentals of circuits: Discrete independent electric devices connected through wires may be analyzed
• 33 Magnetic fields: The magnetic force field is associated with charges in motion (current).
