## Introduction
In this post we will derive an expression for potential field due dielectric material.
For simplicity we will assume that dielectric slab is placed between two charged plates.
## Background
The electric field inside conductor must be zero when it is in electrostatic equilibrium.
This happens because free charges inside conductor move under electric field until they reach equilibrium.
As an example let us consider two plates which are oppositely charged as shown below:

Here we will assume that $+Q$ charge is distributed uniformly over plate $A$ having area $A$.
Similarly $-Q$ charge is distributed uniformly over plate $B$ having area $A$.
Now let us calculate electric field due this configuration.
We know that electric field due point charge is given by:
$$ E = frac{1}{4pi epsilon_0} frac{q}{r^2} $$
where $epsilon_0$ is permittivity constant.
Using this formula we can calculate electric field due plate $A$ at distance $x$ from plate $A$.
$$ E_A = frac{1}{2epsilon_0} frac{Q}{Ax} $$
Similarly we can calculate electric field due plate $B$ at distance $x$ from plate $A$.
$$ E_B = -frac{1}{2epsilon_0} frac{Q}{A(1-x)} $$
Here negative sign indicates that direction is opposite.
Now total electric field at distance $x$ from plate $A$ is given by:
$$ E = E_A + E_B = frac{1}{2epsilon_0} left( frac{Q}{Ax} - frac{Q}{A(1-x)} right) $$
$$ E = frac{Q}{2epsilon_0 A} left( frac{1}{x} - frac{1}{1-x} right) $$
$$ E = -frac{Q}{2epsilon_0 A} left( frac{1-x-x}{x(1-x)} right) $$
$$ E = -frac{Q}{2epsilon_0 Ax(1-x)} $$
We know that electric field between two oppositely charged plates having potential difference $V$ is given by:
$$ E = -frac{V}{d} $$
where $d$ is distance between plates.
Comparing both expressions we get:
$$ d = x(1-x) $$
Now potential difference between two plates can be calculated by integrating electric field between two plates.
$$ V = -int_{x=0}^{x=d} Edx $$
$$ V = -int_{x=0}^{x=d} -frac{Q}{2epsilon_0 Ax(1-x)}dx $$
$$ V = int_{x=0}^{x=d} frac{Q}{2epsilon_0 Ax(1-x)}dx $$
Now we will solve this integral using partial fraction decomposition.
Let us assume that:
$$ frac{Q}{2epsilon_0 A}cdotfrac{1}{x(1-x)} = frac{alpha}{x} + frac{beta}{1-x} $$
So we get:
$$ Q = (alpha + beta)x - alpha x^2 $$
Comparing both sides we get $alpha + beta = Q$ & $alpha = Q$
So $beta = Q - Q = Q$
Now substituting values we get:
$$ V = int_{x=0}^{x=d} (frac{alpha}{x} + frac{beta}{1-x})dx $$
$$ V = [alpha ln(x) - beta ln(1-x)]_{x=0}^{x=d} $$
$$ V = [alpha ln(x) - beta ln(1-x)]_{x=d} - [alpha ln(x) - beta ln(1-x)]_{x=0} $$
$$ V = [alpha ln(d) - beta ln(1-d)] - [alpha ln(0) - beta ln(1)] $$
Since $ln(0)$ approaches infinity so we get:
$$ V = [infty] $$
This shows that potential difference between two oppositely charged plates approaches infinity which means that this configuration cannot exist.
## Dielectric Material Between Plates
Let us now consider another case where dielectric slab having dielectric constant $kappa$, thickness $t$, width $w$, length $l$, area $A=wl$, charge density $rho=frac{-Q}{wt}$ & volume $V=wtl$, capacitance $C=kappa C_0$, where $C_0=epsilon_0 A/d$, polarizability $chi_e=kappa -1$, induced surface charge density $sigma_p=-P_perp=-P_x=chi_erho/kappa$ & polarization vector magnitude $P_x=rho(kappa-1)/kappa$ placed between two oppositely charged plates having charge density $sigma=pm Q/A$. As shown below:

We know that total surface charge density at interface between dielectric material & plate A ($P_A$) & interface between dielectric material & plate B ($P_B$) are given by:
$$ P_A=sigma+sigma_p=-sigma_p=-P_x=-P_perp=rho(kappa-1)/kappa=-Q(kappa-1)/(wtkappa) $$
$$ P_B=-sigma+sigma_p=sigma_p=P_x=P_perp=rho(kappa-1)/kappa=Q(kappa-1)/(wtkappa) $$
As shown below:

Now total electric field inside dielectric slab ($E_d$), outside dielectric slab ($E_o$), inside conductor ($E_c$), outside conductor ($E_c'$), at interface between conductor & air ($E_c''$), inside air ($E_a$), at interface between dielectric material & air ($E_d'$), inside air region outside dielectric material ($E_a'$), at interface between conductor & dielectric material ($E_c'''$) are given by:

where,
* Electric displacement vector inside conductor & outside conductor ($D_c=D_c'$)=Electric displacement vector inside air region outside dielectric material ($D_a'$)=Electric displacement vector at interface between conductor & air ($D_c''$)=Electric displacement vector at interface between conductor & dielectric material ($D_c'''$)=Electric displacement vector inside air ($D_a)$=$D_d=D_d'$=Constant=$Q/A$
* Electric displacement vector inside dielectric slab ($D_d)$=$D_d'=D_o+P_A=D_o-P_B=D_o-P_x$
* Electric displacement vector outside dielectric slab ($D_o)$=$D_a-D_A=D_a'+D_B=D_a'+P_x$
* Electric displacement vector inside air region outside dielectric material ($D_a')=D_a-D_A$
* Electric displacement vector inside air ($D_a)$=$D_o-P_B=D_o-P_x$
So we get,
* Electric field inside conductor & outside conductor($E_c=E_c')=Electric field at interface between conductor & air($E_c'')=Electric field at interface between conductor & dielectric material($E_c''')=Electric field inside air region outside dielectric material($E_a')=Electric field inside air($E_a)=0$
* Electric field inside dielectric slab($E_d)=Electric field outside dielectric slab($E_o)=Electric field at interface between dielectric material & air($E_d')=(D_o-P_x)/(epsilon_okappa)=(D_o-Q(kappa-1)/(wtkappa))/(epsilon_okappa)=(Q/A-Q(kappa-1)/(wtkappa))/(epsilon_okappa)=(Q(wt-A(kappa-1))/A(wt))/(A(epsilon_okappa))=(Q(wt-A(kappa-1))/(A^2(epsilon_o)(wt))$
* Electric field at interface between air region outside dielectric material & air($E_a'')=(D_a-D_A)/(epsilon_o)=(D_a'-D_A)/(epsilon_o)=(D_a'-Q/A)/(epsilon_o)=(D_o-P_x-Q/A)/(epsilon_o)=(D_o-Q(kappa-1)/(wtkappa)-Q/A)/(epsilon_o)=(Q/A+P_x-Q/A)/(epsilon_o)=(P_x/epsilon_o)=(-Q(kappa-1)/(wt))/(wt)cdot((kt))/((kt))=((kt)cdot(-Q(kappa-1))/(w^2t^2))/((kt)cdot(epsilon_o))=(-Q(kappa
