Engineering Entrance Exam

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.
• If the surfaces are closer, the field in that region will be stronger.

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 strong, if the potential decreases sharply over a small distance. The electric field can be calculated using this relationship if the potential distribution is known, and vice versa. It is important for the understanding of the energy transfer in electrostatics and charge dynamics.

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. 
The electrostatic potential helps in quantifying the energy configuration of charges. The unit is volt (V), where 1 V = 1 J/C. 

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 selection process is completed, the University will release the merit list on its official website. All the candidates, whose name is on the merit-list, are required to appear for the counselling/ interview process for seat allocation and document verification process. 

IIT Roorkee offers various BTech and BTech Integrated courses via JEE Advanced exam scores. Candidates belonging to SC and ST categories acquiring a rank of 700 can get admission to various BTech courses under SC and ST AI quota. Candidates can find those courses separately for ST and SC quota both from the table below:
