Electric Field On The Equatorial Of The Dipole Class 12 Physics Chapter 1 Electric Charges and Fields Notes

#6. Electric Field On The Equatorial Of The Dipole

electric field on the equatorial of dipole

In this case we determine the electric field at a point P which is located on the perpendicular bisector of the line joining two charges. Let the distance of point P from this line be r.

Equation of electric field

E.F due to +q charge at point P

E.F due to -q charge at point P

Hence the direction of electric field due to +q charge and -q charge is different, it can be resolved into vertical and horizontal components.

The direction of dipole moment (P) is from -q to +q and resultant electric field is in direction opposite to the electric dipole moment so negative sign is used (-p) to indicate the direction.

Equipotential Surface Class 12 Physics Electrostatic Potential Surfaces And Capacitance

#4. Equipotential Surface Equipotential is the surface which has equal potential at every point on it. Equipotential surface due to a single point charge are concentric spheres having the charge at the center. All the points on a sphere around a point charge have the same distance (radius) so all have same potential. Equipotential surface for a line charge is cylinder Properties of Equipotential Surface Work done for moving a charge on an equipotential surface is zero The potential difference between any two points on equipotential surface is zero Electric Field is always perpendicular to an equipotential surface Equipotential surface for a single point charge are concentric spheres having the charge at the center Two equipotential surfaces can never intersect.

Capacitor And Capacitance Class 12 Physics Notes

#9. Capacitor And Capacitance What is a Capacitor? The capacitor is the device that is used to store electrical energy. It consisted of two electrical conductors separated by a distance. The space between the conductors may be filled with an insulating material known as dielectric. The ability of capacitor to store charge is known as capacitance . This is the symbolic representation of the capacitor Working Of The Capacitor Before explaining the working of a capacitor, let's consider this basic circuit diagram of parallel plate capacitor. There are two conductors plates separated by a small distance 'd'. The space between the conductors is filled with dielectric. The working of the capacitor can be divided into two parts (1) charging of the capacitor (2) discharging of the capacitor Charging of the capacitor When we connect the DC supply to the capacitor, one plate is connected to the positive plate and the other plate is connected to the negative plate. When the potentia...

Van de Graaff Generator Class 12 Physics Electrostatic Potential And Capacitance

Van de Graaff Generator It is an arrangement established by Van De Graaff to building up high potential difference of order 10^7 volts. It works on the following two principles The charges given to the sphere spread to the outer surface of the conductor if two concentric spherical conductors are connected by a wire, the charges will flow from the inner conductor to outer conductor, whatever be the potential of the conductor. 2. Discharging action of sharp points ( Corona Discharge ) The surface charge density of a conductor is σ =Q/A. which means the charge density is more in small or sharp region. Construction Of Van de Graaff Generator It consisted of a large hollow metallic sphere mounted on two insulated supporting columns. An endless belt of an insulating material (Nylon) is mounted on pulleys P1 & P2 which is run by a motor. ...
