How to get pass marks in Physics in days?

Some students asked me this. These were students who never passed in any of the Physics tests during the year when they were in class 12.


Now that the exams are near, they are eager to pass with least effort.


I consoled them, and said, “If you believe and promise to do what I say, you can get more than pass marks in just  days effort.”


They agreed.


The formula I gave them and which fetched them good marks is listed below.


English: Two students studying English at a Ta...


  1. There are some derivations and constructions which are commonly asked in exams. With the help of your teacher identify the portions and learn them well. Take atleast fifteen such portions. Write and practice. Remember, these five days can change your future for ever.
  2. Write all formulae with explanation of each term in a paper. Use them to solve atleast five numericals from each chapter.
  3. Write all laws and principles and learn them by heart.  Try to write from memory and make sure that you can do it without any mistake.
  4. Practice all diagrams
  5. Revise whatever you learnt


Here you go! Do the above with confidence. Practice well, avoid distractions. Eat healthy food. Pray and practice. YOU WILL WIN

The Physics CBSE exam was tough.It was not beyond the syllabus but it was confusing and was asked in a twisted manner.Almost all the students who prepared for the exams didnot leave any derivations,laws etc.But the saddest part was that they asked the big derivation for just one mark and only very few were asked.And most questions were unexpected ones.
It was painful when I saw that after the exam almost all the students were crying.Sitting for a whole night for studying the derivations,laws etc.. gave nothing to us other than tears.We were happy after the English exam but the Physics exam gave a terror over us about Board Exams.I think 90 %  of the students could not complete saying that it was a lengthy paper.

The preliminary examination of the All India P...

During the exam I could see many sitting with great confusion while few others in a hurry to complete  it and the rest of them sitting sadly.By the grace of God I completed 5 minutes before the alloted time and didn’t leave any question.I hope CBSE will consider us.

Yours sincerely,






Where is electricity stored after it is generated but before it is supplied? (Chat Transcript from FaceBook)

Where is electricity stored after it is generated but before it is supplied?
    • Mahesh Sable Electrical power cannot be stored and,therefore,power plants must produce power as and when demanded.power stations r connected in parallel hence load is equally distributed,electric Power can be adjusted with help of step up or step down transformers.


    • Mathew Abraham Transformer does not increase power


    • Chitraja Rajan The demand for electricity varies randomly within a day itself…so there should be something which should be adjusted according to the demand.


    • Vishnu Mohan G huge capacitors? i think i read somewhere like this.


    • Rajat Sharma

      Hi All, the question is very smart, i think electricity stored before generation is stored in Water(DAM), Uranium Rods(Nuclear), HydroCarbons(Coal, GAS). Electricity can only store when it is in Direct Current format like in Batteries, Capacitor(its a very small time to store/release) Well there are many source where we can store electricity. When electricity is in demand then Power generation takes place within huge Alternators, this powers generation takes places in terms of Phase Shift between all the power Houses across the country, if this phase shift is disturb then power grid fails. after this the transformers come into picture so as to reduce Resistance loses.


    • Kannan Kannan Ps in my little knowledge electricity unable to store continuing process of generater get current


    • Chitraja Rajan at the generation side electricity is high ac current ..if it is converted into dc then there should be large containers to store them and also need suitable convertors to convert it in either form every time


    • Mathew Abraham In modern generators, there are equipment to control the rate of flow of water and in turn rate of rotation as well as the power generated. SO, it is quite right to say that electricity is generated as and when required. When you switch on a device power generation also increases until it reaches maximum capacity. Thereafter we will get less power. Remember the low voltage we suffer during the evening when the power consumption is maximum a few seconds ago · Like
