||-plate capacitor:

• Energy stored
• Energy density
• Capacitance of a ||-plate capacitor

Capacitor with spherical symmetry

• One-sphere capacitor
• Two concentric conducting shells

Capacitor network

• Series-connection vs ||-connection
• Examples and the “Water-Beaker” analogy

Reminders:

• Instructor’s informal session’s on Tuesday. See above for time and place.
