The car moves, dust flies, enemies burn, flowers bloom. This line made no sense here, but what I am going to tell you further will definitely make sense. With my 12 years of experience, I will tell you those topics, note my words, not chapters, we are going to discuss that in the next 30 days, which are those 30 topics on which you should keep an eye. If you want to generate a perfect score, perfect score means 100%. So look, today I am going to talk about what I am discussing, this is going to be a law of average for all the sets. I have sorted out the questions of all the sets of the trends of the last 15 years and averaged them. On that basis, I will proceed further. I am going to present the discussion of second, whatever discussions are there, as I told you, are based on what is coming and what is being asked in the paper, it is not my personal opinion, I am not putting my views here, I am putting the facts in front of you, you can verify.
Introduction :
The first lecture of the Vijeta lecture series was Electrostatics, which I conducted in four hours, in that I got all the questions done, in-text questions, NCERT as it is, I have given you the complete content, let's take the discussion ahead, the entire physics is divided into two books, part one, part two, part one includes everything from electrostatic to EM waves, from which I have taken out 15 topics for you, second, the same for the second book, so let's talk about the issue, if we discuss book number one electrostatics, then first of all, Kalm's law, from Kalm's law, force field and super position, from here you can assume that you will get to see the question and that question will be either directly simple of one mark A numerical question is either a definition or two marks questions can come in which he will ask you definition plus numerical. Second Dapur Dapur is a very lovely unit from which questions come in every examination, in boards, in NEET, in JEE, they are asked, they were asked and will keep on asking. The most important in Dapor is electric field due to Dapor in which you should be able to find out the electric field at azi and equatorial positions and second work done in uniform electric field in which you should have information about torque, you should have information about potential energy. So here a five mark question can be generated. Two mark three mark questions can be generated, that is, it is a very important unit. I am making one star on this.
Important Topics :
Okay, let's discuss next, you can see one mark two mark questions on flux Gauss theorem flux. Gauss's law is a very lovely law, a very lovely theorem and its applications. The same number of four apples, hollow sphere, solid sphere, infinite are needed so that if numerical comes then your time is saved. From this, let us assume that you will 100% get to see a question of three marks or five marks. Okay. Second, if we talk about the unit of potential, then from that, there is a discussion on potential and EV potential surface, of which you should know the basics. You have to do NCERT reading in that. You should know the definitions. You should know the units because questions of one mark come. Every day questions are asked on the unit of potential. Every two-three years, it asks questions only on units. Okay, so questions of one mark and two marks are very probable. Second, from this particular unit, dielectrics and capacitance dielectrics, we know what changes take place when we put material between two plates.
Capacitors, different types of capacitors, combinations of capacitors, all these things are important, good numericals are made from this and children get confused. Here, a question of one mark will come, either a simple definition or a good question, then questions of three and five marks can be generated. You can take a screenshot if you want, but I am not talking about the complete PDF form of Holmes law, I am talking about the microscopic form in which you have to discuss conductivity, resistivity, session time, all these derivations have to be done. I remember we used to find drift velocity also here, so all these derivations are very important, on the basis of this, he will ask you questions and can confuse you. Very important from every examination point of view, NEET JD board, everywhere, this is important, it will be asked.
Books :
Okay, questions of one mark, two marks, three marks can be generated from this. Write down Kirchhoff's law with your eyes closed, it will definitely be asked. 100% if it will be asked then I have made stars on both of these as well. Here I have made stars on both of these as well. It used to come, it will keep coming. Okay 100% questions will come from this. Only numericals will come on the square, not theory. And that question can be of three or five marks. The next thing is the heating effect of current, on which numericals of two marks and three marks are made. So here I have written two and three marks. Okay, the next discussion is coming on magnetism, from which Bio-Savat law and its applications, its derivation can come. Formula can come. Many times it confuses us in the formula. It asks for vector form, then children get confused. Where does square come, where does cube come, where did r cap multiply, why did it multiply.
Study Plan :
All those things are very important. Magnetic force and torque, on which numericals are asked. There is a lot of content of three marks and five marks. This discussion of three marks or five marks can be found here. Let us take the discussion further. Magnetic damper and magnetic field lines. Magnetic damper magnetic field lines are asked very rarely so I wrote ahead of it rarely but still in 2023 and 24 one mark questions were asked and in 2020 two mark questions were asked okay in different sets so next discussion is magnetic flux and lens law analysis and questions of magnetic flux and lens law see magnetic flux when you start basically EMI then the first thing that comes is flux then we find out that okay that is the change in flux due to which the whole game is going on and then we talk about Faraday law and then we talk about direction magnetism three mark questions can be seen next thing inductance and ac generator numericals is very probable two-three five mark numericals can be seen from this AC circuit and devices numericals are asked a lot what is inductance called inductive reactance apart from that what do you call capacitance Their circuits, phasor diagrams, after phasor diagram, ray resonance, all these things come in analysis only, so two and three marks in EM waves, displacement current, Maxwell's equation, this brother is asked, derivations and questions of two marks and three marks are asked in abundance, so this was your discussion of book number one, same to same 15 topics for the next book, for the second book.
