Capacitors and capacitance (physics)

CAPACITORS AND CAPACITANCE  
A combination of two conductors placed close to each other is called a capacitor. One of the conductors is given positive charge and the other is given negative charge. The conductor with the positive charge is called positive plate and the other is called negative plate. The charge on positive plate is called the charge on the capacitor and the potential difference between the plates is called the potential of the capacitor. 
For a given capacitor,the charge Q on the capacitor is directly proportional to the potential difference V between the plates. 
   Q=CV
The proportionality constant C is called the capacitance of the capacitor. It depends on the shape, size and geometrical placing of the conductors and the medium between them. 
The SI unit of capacitance is coulomb per volt which is written as farad. The symbol F is used for it. This ia large unit on normal scales and microfarad is used more frequently. 
To put equal and opposite charges on the two conductors they may be connected to the terminals of a battery .Here we state the following properties of an ideal battery. 
(a) A battery has two terminals.
(b)  The potential difference V between the terminals is constant for a given battery. The terminal with higher potential is called the positive terminal and that with lower potential is called the negative terminal. 
(c)  The value of this fixed potential difference is equal to the electromotive force or emf of the battery. If a conductor is connected to a terminal of a battery ,the potential of the conductor becomes equal to the potential of the terminal.

KINGDOM PROTISTA NOTES

LOCOMOTION AND MOVEMENT

Types of Movements
On the basis of structure, three basic types of movements occur in the cells of human body namely
amoeboid, ciliary and muscular.
(i) Amoeboid or Pseudopodial Movements :
Due to the streaming of protoplasm or cytoplasm, the
surface of the cell forms false feet or pseudopodia. The old pseudopodia are replaced by the new
pseudopodia and therefore the formation and withdrawal of it allow the cell to change its shape regularly.
As Amoeba, WBC, and macrophages show pseudopodial movements they do not have a fixed shape.
The leucocytes and macrophages reach each and every part of the body and engulf the antigens or
pathogens through these pseudopodia.
(ii) Ciliary Movements :
The free surface of the cells has short fine hair-like projections called cilia. The
movement of these projections (cilia) is called the ciliary movement. The oar-like activity of the cilia creates
a water current which helps in the movement of various structures. The tubular structures of the human body
such as respiratory tract, reproductive tract are lined by ciliated epithelium and help in the movement
of various substances. In oviduct, cilia provide the motive force for the passage of ova. Coordinated
movement of cilia in trachea helps in the removal of dust particles inhaled along with atmospheric air.
Spermatozoa and protozoa have flagella for locomotion and movement,

(iii) Muscular Movement :
In humans, movement of limbs, jaw, tongue and other body parts occur due to
contraction of muscles. The muscles contract and relax rhythmically to produce movement and are used
effectively for locomotion.

NCERT FACTS U NEED TO KNOW

The National Council of Educational Research and Training (NCERT) is an autonomous organisation, which was set up in 1961 by the Government of India. The NCERT council publishes textbooks for school subjects from Classes I to XII. It also provides sample question papers used in government and private schools across India that follow the CBSE curriculum. Its task is to assist and advise the Central and State Governments about various policies and programmes for qualitative improvement in school education. The major goals of NCERT and its constituent units are to:

Undertake, promote and coordinate research in areas related to school educationPrepare and publish model textbooks, supplementary material, newsletters, journals and develops educational kits, multimedia digital materials, etc.Organise pre-service and in-service training of teachersDevelop and disseminate innovative educational techniques and practicesCollaborate and network with state educational departments, universities, NGOs and other educational institutionsAct as a clearinghouse for ideas and information in matters related to school educationAct as a nodal agency for achieving the goals of Universalization of Elementary Education

NCERT Books & Its Importance

It can be a tedious task to choose the right study material, thanks to the abundant study material available in the market. Many students end up buying the wrong study materials and ruin their scope for getting good marks. Toppers always advise their classmates to make the NCERT textbook the main study material and supplement their efforts with reference books. The reason for this is that the examination is based on these prescribed books, and if you know these textbooks well, you don’t need any supplementary material for the Class X boards.

Check below the top benefits of studying NCERT books if you want to ace the NEET with a good score:

Credible Information

All the NCERT books have been written by experts after doing extensive research on topics. The information is completely authentic and is far better than other sources.

Strong basics and fundamentals

NCERT books include basics and fundamentals on all topics for students. So, it makes it easier for students to understand concepts and prepare in a better way for any competitive exam, be it JEE-Main or AIPMT.

Most of the exam questions are from NCERT Books

One of the biggest benefits of studying from NCERT books is the fact that many questions in NEET are either directly fetched from these books or follow a similar pattern. So, you must not forget to refer to these books for your preparation.

Simple to read and understand

NCERT books have an easy-to-understand language written by experts after extensive research. Since these books are lucid and direct in their approach, it becomes simple for students to understand the technical aspects of topics like kinetics or energy.

NCERT Solutions

The questions and answers given in NCERT textbooks at the end of each chapter are not only important for examination but also essential for understanding the concepts in a better way. Hence, we strongly recommend reading these books thoroughly and making appropriate notes on each chapter that will make revision faster.

These model solutions provide in-depth and step-by-step solutions to all questions in the NCERT textbooks and are an irreplaceable support to students that will help them in learning, working on assignments and preparing for exams.

You can go through NCERT solutions for Class 9 here.

Key points of NCERT Solutions:

The NCERT Solutions provided are entirely FREEThorough and modified answers provided for each question in textbooksCreated by subject matter expertsEasy and quick access to chapter-wise questions and answers

You can find NCERT solutions for all textbooks over here.

NCERT Syllabus

NCERT is responsible for designing the syllabus for all the standards in CBSE board. It also prescribes the syllabus for competitive exams like JEE & NEET. Note that the curriculum designed is based on conceptual learning and not rote learning techniques. So, the NCERT syllabus serves as a single major source for students in the CBSE Board.

Important NCERT Facts

In the year 2016, around 18-20 questions from the biology section were from outside the NCERT syllabus but closely related.Around 40-50% of the questions in physics, around 60% of the questions in chemistry (including around 90-92% of the questions from organic chemistry), and a similar percentage of 90-92% of questions from biology are generally sourced from these textbooks.Most of the pictorial questions you see in the exam are sourced from the NCERT textbook itself, hence memorizing these images from the textbook by heart can be a huge advantage to your preparation.

So, the syllabus given by the CBSE for board classes is completely based on NCERT. If you go through the last 10 years’ exam question papers of board classes, you will find that most of the questions have been asked from the prescribed textbooks. If you want to achieve 90+ percentage in the board exam, then make a habit of reading these books on a regular basis. Each and every line written in these books is very important for board exams. Try to solve all the exercise questions given at the end of every chapter to get the desired result.

Frequently Asked Questions (FAQs)

I am studying from NCERT books and I have completed the latest CBSE Sample Papers. Will I be able to score good marks (say 80% or more)?
Ans. Marks scored by any student depend upon their preparation and performance during the examination. The students are advised to remain focused and do their best. But reading NCERTs would make you strong in the fundamentals, which can directly or indirectly help you answer many questions.

What’s the best way to read the NCERT books?

Ans. Go through the questions at the end of each chapter and then read the chapter. This would help understand the comparative significance of each topic and event, and questions are more likely to be asked from important topics.

Do I  need to make notes of NCERT books?

Ans. Just highlight the important points and revise them at a later stage of preparation.

How many times should I read NCERT books?

Ans. It completely depends on your grasping power. Anyhow, just don’t keep it for the last minute. It should be read and understood at least 3 months before the prelims. Keep a target before starting and try to stick to it so that you don’t lose focus.

How does the textbook help in the JEE Mains?

Ans. NCERT textbooks certainly increase your understanding of various topics and also trains you to answer questions in a simple and precise manner as the language in the textbooks itself is easy to understand.

Which edition is better: old or new?

Ans. Both the editions are good enough. But for Modern Indian History, the old book (Bipan Chandra) is preferable as questions tend to be picked from it directly.

So, that’s all for today, folks!
