Dielectric Materials & Polarization
Inside this lesson
- Describe what makes a dielectric different from a conductor in electrostatic equilibrium
- Apply the multiplicative substitution C_dielectric = ε_r × C_vacuum to the parallel-plate, coaxial, and spherical geometries
- Compute the polarization vector P = ε₀(ε_r − 1)E given the field inside the dielectric
- Relate the polarization to the bound surface charge density σ_b = P at a normal interface with no free charge
