Question

What is When Dielectric is Partial Filled between the Plates?

Answer

When Dielectric is Partial Filled between the Plates - If a dielectric slab of thickness t(t < d) is inserted between the plates as shown. Then, E = Electric field between the plates, E_i = Induced electric field in direction. E' = (E - E_i), the reduced value of electric field in the dielectric. i.e. C' = Q/V' ⇒ C' = ε₀A/(d - t) + 1/K
