JEE-Advanced is for admission to Indian Institutes of Technology (IITs), and Indian School of Mines Dhanbad.

Candidates who passed JEE mains and are in Top 20 percentile in there respective board  are allowed to sit in this test.

Nearly 1.5 lakh student appear for this examination every year. This was previously called IITJEE

What is Electrical engineering

Electrical engineering is a field of engineering that generally deals with the study and application of electricity, electronics, and electromagnetism.

Electrical engineers design, develop, test and supervise the manufacture of electrical and electronic equipment or the fitting and implementation of such equipment into more complex systems. Some of this equipment includes electric motors, machinery controls, lighting and wiring in buildings, automobiles, aircraft, radar and navigation systems, and power generation, control, and transmission devices used by electric utilities. The equipment also usually involves chips and microprocessors.

Use of concept of electric potential

We already know about electric field and electric potential. We also know that electrostatic field is completely characterized by vector function E(r). The electric field depicts the force exerted on other electrically charged objects by the electrically charged particle the field is surrounding. Now a question arises why do we need introduction of electric potential when we already have electric field for the description of electric force between charges.

Frequently Asked Questions about JEE (Main)

Question 1: What is the new scheme of engineering entrance examination ?
Ans. It has been decided to hold a Joint Entrance Examination (JEE) from the year 2013 for admission to the undergraduate programmes in Engineering in two parts, JEE-MAIN and JEE-ADVANCED. Only the top 150000 candidates based on performance in JEE MAIN will qualify to appear in the JEE ADVANCED examination.
Admissions to IITs will be based only on category-wise All India Rank (AIR) in JEE ADVANCED, subject to condition that such candidates are in the top 20 percentile (category wise) in their respective Boards/Qualifying Examinations.

Admission to NITs will be based on 40 % weightage

What is heat?

1)The mean energy transferred between the two system as a result of pure thermal interaction is called Heat.It is the transfer of energy from the higher temperature object to a lower temperature object.

2) The total amount of energy transferred as heat is conventionally written as Q for algebraic purposes. Heat released by a system into its surroundings is by convention a negative quantity (Q < 0); when a system absorbs heat from its surroundings, it is positive (Q > 0).

3) Heat is similar to work as both represent ways of transferring the energy.
