Launching a Friendly Physics Website for Teachers & students

http://www.physicsbeckons.com

Dear Teachers/students,

With the number of posts in the blog growing, the search for relevant content became difficult.In order to make the content well arranged & user friendly, we are launching a website:

http://www.physicsbeckons.com

It classifies as well as clubs the posts pertaining to a particular unit in a single site.

This will facilitate learning & make it enjoyable.

Some special features of the site are:

  • Well defined menu
  • Classification of content (Unitwise)
  • Different sections like Videos, notes, assignments etc.
  • Solved CBSE Physics papers
  • Sample papers for practice
  • MCQs for Conceptual Clarity
  • Tips & Tricks for Low & High achievers
  • A special section on TECHNOLOGY AIDED TEACHING (TAT) to empower the teachers in classroom interactions 

Happy Teaching/Learning!

Examination 2015: Countdown begins…..III (Practicals).

Examination 2015: The Countdown Begins……III

The examination season has begun. The first crucial stage of C.B.S.E examination is the practical examination which must be on now or round the corner and would probably be over by 15th February 2015. This period offers you with a golden opportunity to prepare a few topics for the theory examination as well. The practical syllabus has 3 parts–

1.      Electricity

2.      Ray Optics

3.      Semiconductors

So before you go in for your practical examination, prepare these topics well.

Viva-voce questions for the three parts are being posted for you.

My personal experience over various years has shown that a large no. of students fail to perform well in Viva-voce even if they know the answers because they can’t express themselves.

So I would advise you to make a group (of students) if you have not done so far. Plan preparation and discuss the questions with each other. This will give you much needed practice and confidence to express yourself when you actually go for the viva; an important part of the practical examination.

Here are the questions for you:

Viva-voce- Electricity

Important diagrams:

  • Meter bridge
  • Potentiometer circuits
  • Conversion of galvanometer to ammeter & voltmeter

Viva-voce- Ray Optics

Important diagrams for this sub-unit

  • Ray diagrams for image formation by concave/convex mirrors and lenses
  • Path of light ray through prism (Derive relevant relations and memorise them)

Viva-Voce – Semiconductors 

Important diagrams for this sub-unit

  • Symbols of different types of diodes : pn junction, zener diode,LED etc.
  • Forward & Reverse biasing
  • Circuit for study of forward  & reverse characteristics of pn junction
  • Circuit for study of reverse ch of zener diode
  • Symbols of pnp and npn transistor
  • Circuit for study of characteristic curves of transistor in common emitter mode

It is also advisable to practice diagrams for half wave & full wave rectifier. The theory should be carefully prepared if the project you selected is based on electronic devices.

Needless to say that the practice will help you in CBSE theory exams well.

Remain relaxed when you are called for viva. Most of the examiners are friendly and will try to get the best out of you.

So get started.

HAPPY LEARNING!

Practicals-III

Viva-voce Electrtonic Devices

The examination season has begun. The first crucial stage of C.B.S.E examination is the practical examination which must be on now or round the corner and would probably be over by 15th February 2014. This period offers you with a golden opportunity to prepare a few topics for the theory examination as well. Remember the theory paper also contains a practical based question of 2 – 3 marks.

As detailed earlier, the practical syllabus has 3 parts –

1.      Electricity

2.      Ray Optics

3.      Semiconductors

So before you go in for your practical examination, prepare these topics well.

Viva-voce questions for part 1 & part 2 have been posted earlier..

Part III is here for you. May I add that this is only a collection of viva questions from your practical books but in a form you will find handy to use.

It is advisable to make a group of students if you have not done so far. Plan preparation and discuss the questions with each other. This will give you much needed practice and confidence to express yourself when you actually go for the viva; an important part of the practical examination
