Examiner (E): What was the experiment allotted to you?

Students(S): Sir, I was assigned the experiment to determine the internal resistance of a primary cell using potentiometer.
E: OK, Tell me the principle of a potentiometer

S: Sir. The principle of a potentiometer is that the potential drop across any length of a wire of uniform cross section and composition and carrying a constant current is directly proportional to the length.
E: Good. What is internal resistance?

S: The resistance offered by the electrodes and electrolyte of a ....etc

ABOUT THE BOOK:
This book is designed to meet the course on Engineering Physics Practical of engineering curriculum for the First Year engineering students.
Laboratory work is an important part of the process of learning physics where students apply their knowledge practically.
As no textbook available on the market on Engineering Physics dealt with the experimental part in detail and so in the classroom lecture, the authors
bring out this book. The authors present this book in a very lucid style such that even a below average student ca ....etc

My experience of board practicals

The day started off really early. I woke up at 6:00 am, which isn t usual, and as soon as I woke up, I could feel something tingling inside me. I wasn t alright and my heart was racing. Damn! I was nervous and I was arrested in thoughts and went on to the extent of imagining how the examiner would look like.

With such mixed feelings embedded deep inside me, I finally got ready and sat to revise for the last one hour. I got my books and went on to the room. Slogged for a bit but I wasn t satisfied with ....etc

physics practical viva questions for bsc

Q.1: Define surface tension?
Ans. The tangential cohesive force acting along the unit length of the surface of a liquid
T = F / L
Where F = total force along a line
L = length of the line
In this experiment:
F = m g = weight of the pan + weight in the pan.
L = 2 (length of the slide) + 2 (breadth of the slide).
Sometime we neglect the breadth since it is very small.

Q.2: What are units of surface tension in C.G.S. and S.I. (M.K.S.) system?
Ans. Dynes / cm (C.G.S.)
Newton / meter (M.K.S.)

Q.3: What ....etc

1. What is semi conductor diode laser?

Semiconductor diode laser is a specially fabricated pn junction diode. It emits laser light when it is
forward biased.

2. What is LASER?

The term LASER stands for Light Amplification by Stimulated Emission of Radiation. It is a device
which produces a powerful, monochromatic collimated beam of light in which the waves are coherent.

3. What are the characteristic of laser radiation?

Laser radiations have high intensity, high coherence, high monochoromation and high directionality
with less divergence.
