Engineering Entrance Exam

When placed in an electric field, polarization is the alignment of dipole moments in a dielectric material. In a dielectric, molecules are randomly oriented. When an electric field is applied, it creates induced dipoles by slight shift in molecules from positive to negative. This weakend the net fie

In an electric field, energy density is the amount of energy stored per unit volume . For a linera or vacuum dieletric, it is given by:

E is the electric field magnitude and ?0  is the permittivity of free space. 

Where every point has the same electric potential, it is an equipotential surface:

The main characterstics include:

• Two equipotential surfaces never intersect.
• The electric field is always perpendicular to an equipotential surface.
• Equipotential surfaces are parallel planes in a uniform electric field.
• I

The negative gradient of the electric potential is called an electric field. The electric field points in the direction of the steepest decrease of potential. The electric field is defined in a simpler terms as equal to the change in potential per unit displacement.  The electric field is stron

At any point, the electrostatic potential is the amount of work done in bringing a unit positive test charge from infinity to that point in an electric field. It is done without acceleration. It is denoted by V and it is a scalar quantity.
? =? /Q
where? is the work done and q is the test charge. 

For BTech admission at GNDU RC Jalandhar, it is mandatory to appear for the JEE Main entrance exam. In addition to this, candidates must have passed Class 12 with at least 50% aggregate.  Further, candidates must participate in the counselling round for the seat allotment procedure. After the s
