Lecture: 10 Capacitor & Dielectrics – II (iq06)

Demo: Energy stored in a capacitor

A simple example: C₁, C₂ in series connected to a battery.

Dielectrics:

• Dielectric constant
• Capacitance in presence of dielectrics
• Microscopic picture, induced charge (or polarized charge) Q_ind

Energy stored: U vs U’

• Fixed Q case
• Fixed V case

Energy density
