Dual plate capacitor with two dielectric slabs

Click For Summary
SUMMARY

The discussion centers on a dual plate capacitor configuration featuring two dielectric slabs with differing permittivities. The primary inquiry is whether charge accumulates at the interface of the slabs, given that they are insulators. It is established that the charge at the interface is influenced by the permittivity of the materials and their arrangement, specifically whether the slabs are in contact. The correct terminology is emphasized, noting that the relevant property is permittivity, not permeability.

PREREQUISITES
  • Understanding of capacitor theory and operation
  • Familiarity with dielectric materials and their properties
  • Knowledge of electric field concepts and polarization

Homework Statement



Dual plate capacitor with two dielectric slabs placed between the capacitors and a battery supply's a voltage across the capacitors. The slabs are not equal in dielectric permeability. What is the charge at the interface of the two slabs?

Homework Equations





The Attempt at a Solution



Would the charge be zero between them since insulators don't let charge through or would there be a way for the charge to develop between them? I can't find any information talking about the space between them.

You could have a look at what happens to polarization charges.
 


1. It's permittivity, not permeability.

2. Are the two dielectric slabs touching each other?
