Question

find and expression for the capacitance of a parallel plate capacitor with a dielectric slab in between the plates​

Answer 1

Let the two plates are kept parallel to each other separated be a distance d and cross-sectional area of each plate is A.

• Electric field by a single thin plate E′=2ϵoσ
• Capacitance C=VQ.
• Thus we get capacitance of parallel plate capacitor C=dAϵ
