Briefly explain the use of Zener diode as a dc voltage regulator with the help of a circuit diagram. Obtain the expression for the mutual inductance of two long co-axial solenoids S1 and S2 wound one over the other, each of length L and radii r1 and r2 and n1 and n2 number of terns per unit length, when a current I is set up in the outer solenoid S2. Based on the recommendations of the Education Commission 1964-66 , in 1968 the first national policy statement on education was issued. Write the expression for current sensitivity of the galvanometer.
The detailed and necessary information help the students to make notes easily to prepare for the exams. Inverse Trigonometric Functions Now comes the chapter number two: inverse trigonometric functions. Electrostatic Potential And Capacitance 3. This would ultimately lead to a good score on their board exam. Other than given exercises, you should also practice all the solved examples given in the book to clear your concepts on Alternating Current. You will have to give time for your studies as well as acquiring knowledge from your teachers and tutors, but first of all, it starts with you.
The contribution of eminent scientists such as Nicola Tesla, George Westinghouse and others towards Alternating Current has helped to develop laws on the topic that the students shall study through this chapter. The Council was formed by merging seven existing national government institutions, namely the Central Institute of Education, the Central Bureau of Textbook Research, the Central Bureau of Educational and Vocational Guidance, the Directorate of Extension Programmes for Secondary Education, the National Institute of Basic Education, the National Fundamental Education Centre, and the National Institute of Audio-Visual Education. Moreover, if you have any doubt or query regarding these solutions you can leave your message in below comment section. The class 12 is really important for the students as the future of the students depend upon the marks secured by them in this examination. After that you will learn about Bayes theorem. If you are in class 11. Electromagnetic Waves In this chapter we study the concept of displacement current and the spectrum of electromagnetic waves.
Propagation of electromagnetic waves in the atmosphere, sky and space wave propagation, satellite communication. The council has been offering training facilities, usually through attachment programmes and participation in workshops, to education workers of other countries. Here we will learn about the basics of integrals and its properties. Nuclei Nuclei is the center most part of an atom where positive charge and mass is concentrated. So you can download this book through Download Button given below. Each and every solution for the given problems and questions are explained here in a sequence to official mathematics textbook.
With the help of diagram, explain the principle and working of a cyclotron. Matter waves-wave nature of particles, de-Broglie relation, Davisson-Germer experiment experimental details should be omitted; only conclusion should be explained. You can share it in the below-given comments section. Studying requires great effort with commitment towards your ultimate goal of seeking good marks and percentage in class 12th examinations. It provides in detail solutions to all the questions provided in the textbook. Congratulations that you have made it. Mass-energy relation, mass defect; binding energy per nucleon and its variation with mass number; nuclear fission, nuclear fusion.
Need for modulation, amplitude modulation and frequency modulation, advantages of frequency modulation over amplitude modulation. Force on a current-carrying conductor in a uniform magnetic field, force between two parallel current-carrying conductors-definition of ampere, torque experienced by a current loop in uniform magnetic field; moving coil galvanometer-its current sensitivity and conversion to ammeter and voltmeter. The topics and sub-topics in Chapter 7 Alternating Current are given below. Given the current amplification factor of the transistor is 100, find the input signal voltage and base current, if the base resistance is 1 kΩ. Chapter- 2: Electrostatic Potential and Capacitance Electric potential, potential difference, electric potential due to a point charge, a dipole and system of charges; equipotential surfaces, electrical potential energy of a system of two point charges and of electric dipole in an electrostatic field.
Students who do regular continuous studies are tend to lose the energy and interest in that subject. Application of Integrals Now the chapter number eight is all about implementing the previous chapter you have learnt. In case, If not working correctly, let me know by commenting. Calculate the rms value of the current in the network. If you have a book in your mobile, you can study wherever you are. And as you might know, we bring something good information every day.
It helps to build a strong foundation by making the concepts clearer and simpler to understand. These practicals should be duly checked and signed by the internal examiner.
