Category Archives: JEE Main

JEE Main  is the prestigious examination in India for admissions to NIT,IIIT and other  state engineering colleges.

It is also the gateway for JEE advanced which is the examination for IIT’s

We  cover all the JEE main related posts here which will be very helpful to students and teacher.

We also give the examination details,syllabus as prescribed the Jee main site

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.

Uses of Capacitor

1) The main purpose of the capacitor is to store charge . If an instantanous strong current is to be flown in a circuit,the best way would be to connect the terminals of the circuit to a charge capacitor

2 A capacitor can store electric energy when disconnected from its charging circuit, so it can be used like a temporary battery. Capacitors are commonly used in electronic devices to maintain power supply while batteries are being changed. (This prevents loss of information in volatile memory.)

How to find workdone by several forces acting on a object

This can be done in these simple steps

1) First draw a free body diagram of the body showing all the forces on it.

2) Carefully choose a X-Y coordinate system so that direction of the motion or direction of force lies in X or Y direction. This will simplfy the Problem

3) Applying Newton’s law find out any unknown forces

H.C Verma Concepts of physics OR NCERT physics books

Many times i have had users ask me a question which book to opt between H.C Verma Concepts of physics and NCERT physics books. My answer is you can keep both the books set for your preparation as NCERT is nice book to learn a good concepts and is according to the exam level of class 11 and class 12.

5 Tips to crack IITJEE Examination

IITJEE papers generally test the basic concept of the subject.So basic concept should be very clear. Concentrate on the basic concepts.Strengthen your fundamentals.Master the basic of each chapter. Do many times so that you know the concept by heart.NCERT books are good for the concept.So first should be to study the NCERT books and familarize all the concepts.HC verma is also good for concept

how to choose your engineering college

Just scoring well in AIEEE is not enough. What is important is to choose the right field of engineering you wish to pursue and which college should you enroll? In this engineering admission season, Learnhub speaks to experts and students to help you choose the right college and stream of engineering. So get clicking to make the correct choice.
In this lesson, we will try to sort out your confusion on what should be the parameters to pick your engineering college. Should brand take precedence over placements or should faculty be given importance over infrastructure? Let’s find out…
