Course overview of electric charge,field and potential. All the  points covered in this course discussed in this lesson.Frictional electricity:induction, coulomb's law,permittivity of the vaccum.detal conceptual explanation. Coulomb force between two charge Q and q given by.F(r)= kQq/r2 and finally 
F(r)= Qq/4πϵr2 i.e proportional to r square.constant k= 1/4πϵ is equal to 9x10^9. Here ϵ is called permittivity of free space.Relation between electric field and potential, concept of equipotential surface. Electric field given by partial differentiation of potential w.r.t position. E=-∂V/∂x,where y&z const.and so on for y& z. In r and θ ,E=-∂V/∂r, where θ const. Change in potential given by dV= -Edr.i.e field is given by differential method and potential is given by integral method.Conductor,insulator and semiconductor,
Electric field inside a conductor.coductor having most no of free electrons, semiconductor less no of free electrons and in insulators having very less no of free electrons. Free electrons also known as conduction electrons.if conductor placed in an electric field(E) then inside the conductor redistribution of electrons started and hence internal  electric field  created (E'). After some time E'=E  and hence redistribution stop. Finally inside the conductor net electric field is zero. Hence in electrostatic electric field inside
A conductor is zero.

Electric potential energy mathematical derivation. Definition and concept behind this.electric potential energy of a system.this is a scalar quantity. Potential venergy of two charge system separated by displacement r is given by
U(r)= Qq/4πϵr.

Electric potential energy (in hindi)

Details of electric potential(V).electric potential energy(U) per unit charge is known as electric potential.reference point taken at infinity. Volt is the unit of electric potential. Joule per coulomb is volt. W(external)= - W(electric)= ΔU change in potential energy of charge particles system. ΔV = ΔU/q. For point charge potential at distance r is given by V(r)= Q/4πϵr.

Electric Potential (in hindi)

Relation between electric field and potential, concept of equipotential surface. Electric field given by partial differentiation of potential w.r.t position. E=-∂V/∂x,where y&z const.and so on for y& z. In r and θ ,E=-∂V/∂r, where θ const. Change in potential given by dV= -Edr.i.e field is given by differential method and potential is given by integral method.

Electric dipole
Electric potential due to dipole
Generalised definition of electric dipole
Electric field due to dipole
And some special case. Electric dipole moment (P)= qd, where q= electric charge and d= seperation between -ve and +ve charge.direction of dipole from -ve to +ve charge and also it is axis of dipole. Electric potential of dipole at r&θ position, V= Pcosθ/4πϵr2. 
Electric field E in radial and transverse (θ) direction. E(r)= 2Pcosθ/4πϵr3, and E(θ)=Psinθ/4πϵr3. Resultant field at point p is calculated by 
vector sum of E(r) and E(θ).

Torque on an electric dipole placed in an electric field,
Potential energy of a dipole placed in a uniform electric field.
Torque (τ)= PxE cross product. And potential energy U= -P.E dot product,whete P= electric dipole moment and E = electric field. Torque is always opposite to the angular displacement.

Conductor,insulator and semiconductor,
Electric field inside a conductor.coductor having most no of free electrons, semiconductor less no of free electrons and in insulators having very less no of free electrons. Free electrons also known as conduction electrons.if conductor placed in an electric field(E) then inside the conductor redistribution of electrons started and hence internal  electric field  created (E'). After some time E'=E  and hence redistribution stop. Finally inside the conductor net electric field is zero. Hence in electrostatic electric field inside the conductor is zero.
