The Slab That Pulls Itself In
You'll learnwhat a dielectric does to a capacitor, why the answers flip with the wiring, and why a neutral slab gets pulled into the gap.
Slide a plastic slab between the plates and the capacitor holds four times as much. What happens to the charge, the voltage and the energy depends on the wiring. Twelve short steps; press Next for each one.
the slab multiplies C by κ · the wiring decides every other arrow
Before you start
What you're looking at
The capacitor from the last topic, with a violet slab sliding into its gap. Thick marks are free charge on the plates; thin marks on the slab are bound charge.
The question
What does the slab change, and what decides which way everything moves?
