Why can't we use a galvanometer directly for the measurement of voltage?

Since Galvanometer is a very sensitive device. If a low value of current pass through the galvanometer, then it may burn of explode. Therefore, it is converted into voltmeter by connecting the coil of the galvanometer with a low resistance in parallel combination ammeter is made. While current is directly proportional to Voltage by Ohm's Law.

Because Galvanometer is used to detect electric current not voltage.

I have 3 subjects in my graduation (B.Sc) Physics, Maths and Chemistry, I am confused about what subject should I prepare for in IIT JAM?

Rakshit Prabhakar

Well, if you have Physics, Chemistry, and Mathematics, all three in your Bachelor's degree you should first understand and analyze that which subject you like the most and you are highly interested in. Then devote atleast a year and evaluate the scope of M.Sc in that particular subject, study it and then select the subject. Don't be in a rush, take your time.

How many questions will be asked from the physics section in the SITEEE exam?

Samridhi Mishra

The physics section will hold 30 marks weigtage in the SITEEE question paper. There will be 15 MCQs out of the class 11th and 12th physics syllabus of CBSE, each of 2 marks.

What are the most important topics from the SITEEE Physics syllabus?

Samridhi Mishra

The complete SITEEE exam syllabus is important. However, students must pay extra attention to a select few topics of the SITEEE physics syllabus like Kinematics, Laws of Motion, Work, Energy, and Power, Gravitation, Thermodynamics, Oscillations and Waves, Electrostatics, Current Electricity, Magnetism, Electromagnetic Induction, Optics (Ray and Wave), the Dual Nature of Radiation and Matter, Atoms and Nuclei, and Semiconductors.

What is the SITEEE syllabus for Physics?

Samridhi Mishra

The SITEEE syllabus for physics is based on the class 11tha dn 12th syllabus of the CBSE curriculum.

What are some books to prepare for JEE Advanced physics?

Mamta Bankoti

Well, that's great, as you are preparing for JEE Advanced Physics. From my research, I would like to recommend some of the books and resources that will help you learn the basics and understand the concept:

1. Concept of Physics (Vol 1 and 2) by H.C. Verma

2. Understanding Physics Series by D.C. Pandey (Arihant)

3. Fundamentals of Physics by Halliday, Resnick and Walker

4. Problem in General Physics by I.E Irodov

5. Physics Galaxy by Ashish Arora.

6. Previous Year Question Book (likee PW 48 Years/Oswaal JEE Advanced Paper)

4. Problem in General Physics by I.E Irodov

5. Physics Galaxy by Ashish Arora.

6. Previous Year Question Book (likee PW 48 Years/Oswaal JEE Advanced Paper)

The first book to read would be 'Concepts of Physics (vol 1 and 2)' by H.C. Verma Why you should read this book first: because it will build strong basics, and you will understand the concept easily. This book explains each and every topic in simple language and helps you to learn problems step by step.

After that, you can read the 'Understanding Physics Series' by D.C. Pandey (Arihant). This book is divided into 5 parts (Mechanics 1, Mechanics 2, Waves and Thermodynamics, Electricity and Magnetism, and Optics and Modern Physics). This book has a lot of JEE Main and Advanced level questions that will help you to practice every type of problem.

The third book to read is 'Fundamentals of Physics' by Halliday, Resnick, and Walker. This book gives you a deep understanding of theory and helps you with the physics concept. This book will improve your theory and alternative methods.

The fourth book you can read is 'Problem in General Physics' by I.E. Irodov. This book has one of the toughest problems for JEE Advanced. This book helps you to develop speed and accuracy.

The fifth book you can read is 'Physics Galaxy' by Ashish Arora. This book covers all the conceptual gaps that you will not find in other books and contains advanced illustrations and tricky problems.

The last book would be 'Previous Year Question Book (like PW 48 Years/Oswaal JEE Advanced Paper).' This book helps you to understand the real exam patterns. You will get to know how the questions are asked, and you will learn how to apply what you have learned. It will not only improve your timing but also build confidence in you.

I hope this will help.
