Galvanometer
A galvanometer is an electromechanical instrument for detecting and measuring electric current. The most common use of galvanometers was as analog measuring instruments, called ammeters, used to measure the direct current (flow of electric charge) through an electric circuit. A galvanometer works as an actuator, by producing a rotary deflection (of a pointer), in response to electric current flowing through a coil in a constant magnetic field.
Galvanometers developed from the observation that the needle of a magnetic compass is ....etc

CBSE class 12 physics investigatory Projects tangent galvanometer
CBSE reintroduced investigative projects in physics is AISSCE WEF 2013 applicable to students who are in class XI during the academic year 2011-12 and 2013 Board Exam writing.

Work is now only for demonstration purposes. The student must perform a minimum of 15 experiments per year.

For the exam, he or she must perform two experiments; one of the section a and section B one.

The proposed investigative PROJECTS CLASS XII

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

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
